[U-Boot] [PATCH 07/10] arm: Add option to display customised memory information

[Simon Glass]

Some boards want to report more than just memory size. For example, it
might be useful to display the memory type (DDR2, DDR3) or manufacturer.

Add a weak function to support this requirement.

Any example of the DRAM: output is below, just for illustration:

U-Boot 2011.12-02470-gd64a0f8-dirty (Sep 14 2012 - 10:46:39) for SMDK5250

CPU:   S5PC520 @ 1700MHz
I2C:   ready
DRAM:  2 GiB Samsung DDR3 @ 800MHz
MMC:   S5P MSHC0: 0, S5P MSHC1: 1
Using default environment
