ARM: at91: fix nommu build regression
The newly introduced support for SAMA5D4 added access to the 'AT91_ALT_BASE_SYS' register area, but failed to define the symbols in the case when CONFIG_MMU is disabled. We really should not hardwire addresses like this any more, but as a small fixup, this patch just adds the missing definitions for the nommu case, which gets at91x40_defconfig and any configuration of sam9 and sama5 with MMU disabled back to work. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 726d32bf79ef4 ("ARM: at91: SAMA5D4 SoC detection code and low ...")
