[U-Boot] [PATCH v1 1/2] board: toradex: colibri_vf: efi_loader: unset CONFIG_EFI_UNICODE_CAPITALIZATION

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Unset CONFIG_EFI_UNICODE_CAPITALIZATION on boards with tough size
restrictions.

This is analogous to commit a90bf07afc43
("efi_loader: unset CONFIG_EFI_UNICODE_CAPITALIZATION").

[U-Boot] [PATCH v1 2/2] imx: mkimage: add size check to the u-boot.imx make target

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

The make macro to check if the binary exceeds the board size limit is
taken straight from the root Makefile.

Without this and e.g. enabled EFI Vybrid fails booting as the regular
size limit check does not take the final u-boot.imx binary size into
account which is bigger due to alignment as well as IMX header stuff.

Added both patches to u-boot-imx, check is effective, now size is too
much and build fails:

Sure, what kind of a tool chain are you using? Might just be that the
GCC 8.2 I was using does a better job in optimising stuff. Yep, with
GCC 7.3.1 it also fails at my end! I guess then we have to drop EFI
entirely but I doubt Mr. Graf will be happy...

I definitely wouldn't be happy, but I've seen us run into tight 
situations with Vybrid before. So yes, if your platform really a) 
doesn't want to ever support EBBR and b) really has very tight size 
constraints, disabling EFI_LOADER is perfectly fine with me.

Yes, I'm fully aware of EBBR having attended Grant's talk in Edinburgh
but especially those older raw NAND platforms are probably not the best
candidates for any of this. Unless, of course, we would put some more
effort transitioning them all to SPL and what not to overcome e.g. such
SRAM limitations. I will send a v2 which disables EFI for now.

I sent a v2 additionally dropping CONFIG_CMDLINE_EDITING and SPI
support saving another 8 Kb which for me makes it work right back to
GCC 6.1.1 which I believe is anyway about as far back as one can go
even compiling U-Boot. Can you please give that another go?

Merged the patchset, it works in my build. I will send PR to Tom.
