[coreboot] Bricked Lenovo T60

[Damien Zammit]

Hi folks,

Thanks #coreboot for all your help with my laptop, I learnt a lot today
from you all.
Unfortunately my first attempt at installing coreboot has resulted in a
bricked laptop.

I tried to cheat by making an educated guess of the SPI chip model
without pulling my laptop to bits to verify.  However, it seemed right
according to the responses i was getting from flashrom -V for the failed
chips, since the manufacturer id and model id I was getting from
flashrom matched the datasheet specs for a particular chip.

I downloaded and compiled the crossgcc toolchain.

I created a patch for flashrom and proceeded to read my flash.
I got a successful read from flashrom and dumped my vgabios.

I compiled coreboot for T60 and followed the wiki grabbing the 3 patches
for Lenovo stuff and inserting my custom SMBIOS details in the config.

Once i felt happy with my coreboot.rom I followed exactly the procedure
on the coreboot Lenovo wiki to flash my laptop internally.

I have attached here the coreboot config i used, the clues I used to
write the flashrom patch, the flashrom patch i wrote, and the flashing
log.

My current T60 status is "Bricked, in Bucts 1 configuration"

I guess my next step is to pull my laptop to bits without removing the
CMOS battery and see if the flash chip is indeed the one that I
estimated, and perhaps reflash it with coreboot?  I'm not too sure what
to do next but GNUtoo from #coreboot recommends a poloma clip.  Coreboot
team were very very helpful in trying everything to help me and warned
me right at the start I needed a way to recover.  They were right!
