This way platforms that want it can select AUTO_ZRELADDR without issues caused by someone manually also enabling ZBOOT_ROM. Signed-off-by: Olof Johansson <redacted> --- arch/arm/Kconfig | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) Russell King wrote at Friday, October 14, 2011 1:15 AM:
I'll point out that this makes Tegra incompatible with ZBOOT_ROM, which can still be enabled. ZBOOT_ROM=y AUTO_ZRELADDR=y is an invalid configuration at runtime.
Ah, looks like the dependency is only one-way. Since they are mutually exclusive, how about the below?
