From: Tirumala Marri <tma...@apm.com>
APM82XXX is a new line of SoCs which are derivatives of
PPC44X family of processors.
This patch adds support of CPU, cache,
tlb, 32k ocm, bootstraps, PLB AHB bus, DDR and
Some common register definitions.
Signed-off-by: Tirumala R Marri <tma...@apm.com>
---
V1:
* Squash some of the patches.
* add space between "||" and "\".
* Add spaces around operators.
* Unsigned int to u32.
* Add empty line which was removed.
* remove warning "unused variable" in cpu_init.c
V2:
* Removed Defines added to 405ex.
