NEW MAINBOARD: Dell Latitude E6400

Browse source 
This uses a newer coreboot revision, where E6400 support is
available in the master branch. This is another GM45 machine,
but it has DDR2 raminit instead of DDR3. Thanks go to Nicholas
Chin who ported this to coreboot.

A utility is added, written by Nicholas Chin, that can unlock
the flash for internal programming, bypassing Dell's security.
This can be used to flash GNU Boot from the Dell BIOS, without
taking this machine apart; the dell-flash-unlock README contains
instructions for how to do this.

Subject: [PATCH 16/22] fix speedstep on x200/t400: Revert
"cpu/intel/model_1067x: enable PECI"
This reverts commit 70fea013c7ebd6d85a7806748233fcfd76802f5f.
Enabling PECI without microcode updates loaded causes the CPUID feature set
to become corrupted. And one consequence is broken SpeedStep. At least, that's
my understanding looking at Intel Errata. This revert is not a fix, because
upstream is correct (upstream assumes microcode updates). We will simply
maintain this revert patch in Libreboot, from now on.

Subject: [PATCH 17/22] GM45-type CPUs: don't enable alternative SMRR
This reverts the changes in coreboot revision:
df7aecd92643d207feaf7fd840f8835097346644
While this fix is *technically correct*, the one in
coreboot, it breaks rebooting as tested on several
GM45 ThinkPads e.g. X200, T400, when microcode
updates are not applied.
Since November 2022, Libreboot includes microcode
updates by default, but it tells users how to remove
it from the ROM (with cbfstool) if they wish.
Well, with Libreboot 20221214, 20230319 and 20230413,
mitigations present in Libreboot 20220710 (which did
not have microcode updates) do not exist.
This patch, along with the other patch to remove PECI
support (which breaks speedstep when microcode updates
are not applied) have now been re-added to Libreboot.
It is still best to use microcode updates by default.
These patches in coreboot are not critically urgent,
and you can use the machines with or without them,
regardless of ucode.
I'll probably re-write this and the other patch at
some point, applying the change conditionally upon
whether or not microcode is applied.
Pragmatism is a good thing. I recommend it.

Subject: [PATCH 19/22] Remove warning for coreboot images built without a
payload
I added this in upstream to prevent people from accidentally flashing
roms without a payload resulting in a no boot situation, but in
libreboot lbmk handles the payload and thus this warning always comes
up. This has caused confusion and concern so just patch it out.

This reverts commit 44a48ce7a46c36df69f7b2cf3552bf10fa5f61b6.
NOTE:
this is done instead of merging:
https://review.coreboot.org/c/coreboot/+/78623
which is still under review for now
the patch i'm reverting is this one:
https://review.coreboot.org/c/coreboot/+/78270
this was actually only merged the day before i
updated coreboot revs in lbmk to the 12 october rev,
so there's no harm in quickly reverting this for now
however, later on, we will rely on the other patch

Subject: [PATCH] [NOT FOR MERGE] nb/intel/gm45: Make DDR2 raminit work
List of changes:
- Update some timing and ODT values
- Patch RCOMP calibration to better match what MRC binaries do
- Replay a hardcoded list of RCOMP codes after RcvEn
This makes raminit work at DDR2-800 speeds and fixes S3 resume as well.
Tested on Toshiba Satellite A300-1ME with two 2 GiB DDR2-800 SO-DIMMs.

# Dell Laptop Internal Flashing
This utility allows you to use flashrom's internal programmer to program the
entire BIOS flash chip from software while still running the original Dell
BIOS, which normally restricts software writes to the flash chip. It seems like
this works on any Dell laptop that has an EC similar to the SMSC MEC5035 on the
E6400, which mainly seem to be the Latitude and Precision lines starting from
around 2008 (E6400 era).
## TL;DR
### Linux specific
- On Linux, ensure you are booting with the `iomem=relaxed` kernel parameter.
- If you get a "Function not implemented" error, ensure that your kernel has
"CONFIG_X86_IOPL_IOPERM" set to "y". Here are several common locations for
the config and how to check them:
- `zcat /proc/config.gz | grep IOPL`
- `grep IOPL /boot/config`
- `grep IOPL /boot/config-$(uname -r)`
If it says it is not set, then you will need to install or compile a kernel
with that option set.
### OpenBSD
- On OpenBSD, ensure you are booting with securelevel set to -1.
### General
Make sure an AC adapter is plugged into your system
Run `make` to compile the utility, and then run `./dell_flash_unlock` with
root/superuser permissions and follow the directions it outputs.
## Confirmed supported devices
- Latitude E6400, E6500
- Latitude E6410, E4310
- Latitude E6420, E6520
- Latitude E6430, E6530, E5530
- Latitude E7240
- Precision M6800, M5800
It is likely that any other Latitude/Precision laptops from the same era as
devices specifically mentioned in the above list will work as Dell seems to use
the same ECs in one generation.
## Tested
These systems have been tested, but were reported as not working with
dell-flash-unlock. This could be due to user error, a bug in this utility, or
the feature not being implemented in Dell's firmware. If you have such a system,
please test the utility and report whether or not it actually works for you.
- Latitude E6220
- Latitude E6330
## Detailed device specific behavior
- On GM45 era laptops, the expected behavior is that you will run the utility
for the first time, which will tell the EC to set the descriptor override on
the next boot. Then you will need to shut down the system, after which the
system will automatically boot up. You should then re-run the utility to
disable SMM, after which you can run flashrom. Finally, you should run the
utility a third time to reenable SMM so that shutdown works properly
afterwards.
- On 1st Generation Intel Core systems such as the E6410 and newer, run the
utility and shutdown in the same way as the E6400. However, it seems like the
EC no longer automatically boots the system. In this case you should manually
power it on. It also seems that the firmware does not set the BIOS Lock bit
when the descriptor override is set, making the 2nd run after the reboot
technically unnecessary. There is no harm in rerunning it though, as the
utility can detect when the flash is unlocked and perform the correct steps
as necessary.
## How it works
There are several ways the firmware can protect itself from being overwritten.
One way is the Intel Flash Descriptor (IFD) permissions. On Intel systems, the
flash image is divided into several regions such as the IFD itself, Gigabit
Ethernet (GBE) non-volative memory, Management Engine (ME) firmware, Platform
Data (PD), and the BIOS. The IFD contains a section which specifies the
read/write permissions for each SPI controller (such as the host system) and
each region of the flash, which are enforced by the chipset.
On the Latitude E6400, the host has read-only access to the IFD, no access to
the ME region, and read-write access to the PD, GBE, and BIOS regions. In order
for flashrom to write to the entire flash internally, the host needs full
permissions to all of these regions. Since the IFD is read only, we cannot
change these permissions unless we directly access the chip using an external
programmer, which defeats the purpose of internal flashing.
However, Intel chipsets have a pin strap that allows the flash descriptor
permissions to be overridden depending on the value of the pin at power on,
granting RW permissions to all regions. On the ICH9M chipset on the E6400, this
pin is HDA\_DOCK\_EN/GPIO33, which will enable the override if it is sampled
low. This pin happens to be connected to a GPIO controlled by the Embedded
Controller (EC), a small microcontroller on the board which handles things like
the keyboard, touchpad, LEDs, and other system level tasks. Software can send a
certain command to the EC, which tells it to pull GPIO33 low on the next boot.
Although we now have full access according to the IFD permissions, we still
cannot flash the whole chip, due to another protection the firmware uses.
Before software can update the BIOS, it must change the BIOS Write Enable
(BIOSWE) bit in the chipset from 0 to 1. However, if the BIOS Lock Enable (BLE)
bit is also set to 1, then changing the BIOSWE bit triggers a System Management
Interrupt (SMI). This causes the processor to enter System Management Mode
(SMM), a highly privileged x86 execution state which operates transparently to
the operating system. The code that SMM runs is provided by the BIOS, which
checks the BIOSWE bit and sets it back to 0 before returning control to the OS.
This feature is intended to only allow SMM code to update the system firmware.
As the switch to SMM suspends the execution of the OS, it appears to the OS
that the BIOSWE bit was never set to 1. Unfortunately, the BLE bit cannot be
set back to 0 once it is set to 1, so this functionality cannot be disabled
after it is first enabled by the BIOS.
Older versions of the E6400 BIOS did not set the BLE bit, allowing flashrom to
flash the entire flash chip internally after only setting the descriptor
override. However, more recent versions do set it, so we may have hit a dead
end unless we force downgrade to an older version (though there is a more
convenient method, as we are about to see).
What if there was a way to sidestep the BIOS Lock entirely? As it turns out,
there is, and it's called the Global SMI Enable (GBL\_SMI\_EN) bit. If it's set
to 1, then the chipset will generate SMIs, such as when we change BIOSWE with
BLE set. If it's 0, then no SMI will be generated, even with the BLE bit set.
On the E6400, GBL\_SMI\_EN is set to 1, and it can be changed back to 0, unlike
the BLE bit. But there still might be one bit in the way, the SMI\_LOCK bit,
which prevents modifications to GBL\_SMI\_EN when SMI\_LOCK is 1. Like the BLE
bit, it cannot be changed back to 0 once it set to 1. But we are in luck, as
the vendor E6400 BIOS leaves SMI\_LOCK unset at 0, allowing us to clear
GBL\_SMI\_EN and disable SMIs, bypassing the BIOS Lock protections.
There are other possible protection mechanisms that the firmware can utilize,
such as Protected Range Register settings, which apply access permissions to
address ranges of the flash, similar to the IFD. However, the E6400 vendor
firmware does not utilize these, so they will not be discussed.
