[U-Boot] [PATCH v5 1/2] ARMV7: OMAP3: Cleanup extern variables in mem.c

Luca Ceresoli luca.ceresoli at comelit.it
Wed Apr 20 14:27:39 CEST 2011 

Removed boot_flash_* extern variables.
boot_flash_type was totally unused. The other ones were actually constants, so
they have been replaced with #defines in the board config files.
