[SeaBIOS] Re: [PATCH v7 7/8] bootdevice: FW_CFG interface for LCHS values

[Sam Eiderman]

Thanks for the detailed comment Laszlo,

Indeed my e-mail has changed and I only received replies to the
commits where I added this new mail in the S-o-b section, should of
added in all of them.

So as you said it, the problem was actually in using qfw_cfg_get_u32
which assumes the value is encoded LE and has an additional
le32_to_cpu, should have used qfw_cfg_get directly like
qfw_cfg_get_file does.

Regarding qfw_cfg_get_file - I wrote this code when this function did
not exist yet, I think it was added 6 months ago. In any case, I will
use it instead.

Thanks for this.

I will resubmit this entire commit series:
* I will only change code in the last commit (tests)
* I will remove a comment which is now not true anymore
* I will add my new email in S-o-b

Sam
