spl for OMAP4 does not use mmc read/write.
Add CONFIG_MMC_NO_ERASE, CONFIG_MMC_NO_WRITE to platforms where mmc

Use these CONFIGS to remove write/erase code in mmc.c and omap_hsmmc.c
This reduces the spl size by ~1128 Bytes
Are you running into a size limitation again? If not, I think we want
We are always on the border. Minor fluctuations are affecting us. And
our EMU boards(secure devices) are permanently broken due to this. I am
not sure if this one helps EMU devices though.
to wait until we sort out how SPL includes/excludes stuff moving
forward as this shows there's probably a lot of other unused code
being pulled in.
We use -ffunction-sections -fdata-sections and --gc-sections while
building SPL. So, un-necessary stuff will not be included unless the
function pointers are set in some structures and not used. I think that
is what is happening in this case. Other than that I am not expecting
much scope for improvement.
One key experiment I want to do is Thumb mode build. I have some old
patches that I may cleanup and post sometime soon. But Thumb mode had
some tool-chain related issues last time I tried.
