[U-Boot] [PATCH 2/2] integratorap: fixup SDRAM memory size detection

Linus Walleij linus.walleij at linaro.org
Thu Jul 14 01:04:36 CEST 2011


This fixes up the SDRAM memory detection code to work with the
latest relocation code, moves it all into dram_init() and
activates memory size detection for the Integrator AP.
