[U-Boot] [RFC 1/4] MX31: Add struct definition for clock control module in i.MX31.

[Magnus Lilja]

Comment:
The struct is called system_control_registers only because the mxc_nand.c
uses that name. For i.MX31 these registers are called "Clock Control
Registers" so the struct name should be clock_control_registers, while
for i.MX27 they are called "System Control Registers".
