Subject: Add architecture-specific global data
X-Git-Tag: v2013.04-rc1~133
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5cb48582ac05931c66b00b46c60d3ee8c6fc7950;p=oweals%2Fu-boot.git

Add architecture-specific global data

We plan to move architecture-specific data into a separate structure so
that we can make the rest of it common.

As a first step, create struct arch_global_data to hold these fields.
Initially it is empty.

This patch applies to all archs at once. I can split it if this is really
a pain.
