Simon,
I am trying to format a patch to disable MMC in the SPL if
booting main u-boot using BOOTROM, therefore the SPL MMC isn't
needed.
Is the best solution to wrap every header file (rock2.h
firefly-rk3288.h, etc) with ifdefs on the BACK_TO_BROM define?
Or would it be better to move the SPL MMC define into
rk3288-common.h and just have chromebook_jerry undef it like
it does the SPL GPIO code.
With that change, enabling BOOT_TO_BROM shrinks the spl from
32K to 23K.
Note that, firefly-rk3288 use OF_PLATDATA, we will use
u-boot-spl-no-dtb.bin instead of u-boot-spl-dtb.bin, and the size
of u-boot-spl-no-dtb.bin is almost 23K.
The patch would apply if OF_PLATDATA is used too (Although I haven't
tested it). It would just shrink the SPL more right because you don't
need the MMC driver. I wasn't planning to change any of the defconfigs.
Okay, I'll have no objection to your doing it.
@Simon, I think we will update doc/README.rockchip if you insist
on OF_PLATDATA for firefly-rk3288. we no longer use
u-boot-spl-dtb.bin.:-)
