[PATCH 1/2] ARM omap beagle xload_defconfig: do not load drivers from DT

[PATCH 1/2] ARM omap beagle xload_defconfig: do not load drivers from DT

[Alexander Kurz]

The first stage loader must run in SRAM and is limited in size.
Remove unused support to load drivers from DT at this stage and
save precious 9kB of code size.
Regenerating the defconfig removes CONFIG_TEXT_BASE.

[PATCH 2/2] ARM omap beagle defconfig: remove trace initcalls

[Alexander Kurz]

Debug output may be switched on when needed, but should not be on by default.
Regenerating the defconfig removes CONFIG_TEXT_BASE.
