Cover letter [U-Boot] [PATCH v3 0/19] ARM: SPL: Make more generic, merge DaVinci and OMAP
Quoted 18 lines · Tom Rini

Hey all,

The following patch series merges the davinci and omap-common SPL frameworks into a single framework, CONFIG_SPL_FRAMEWORK along with a few small cleanups to the code to make it a little smaller and more flexible. The end result is that davinci can now opt in on SPL-boots-Linux by just setting the right defines and other platforms would just need to adapt to this framework. In my testing, davinci gains between 300 and 700 bytes for this (not enabling the SPL OS feature) and omap4/5/etc lose just a little bit (from the printf->puts changes). I've tested this on omap3_beagle (xM and classic) and omap4_panda. I don't have any davinci platforms that were previously using SPL so I can't boot-test those changes but since everyone sets CONFIG_SPL_MAX_SIZE, we're OK in that department.

To make this series easier to test I've placed it on

I've looked a little into re-reducing the size and the biggest problem I see is that SPI a lot of informational prints that we don't need, strictly speaking, but are nice in a normal U-Boot context. I'm unsure of the best way to quiet these as I don't like the idea of sprinkling

Nice Work !

Tested on a MX35 board.
