[U-Boot] [PATCH 001/159] LCD: Add an option to skip registration as an stdio output

[Lin Huang]

From: Stephane Ayotte <sayotte@tycoint.com>

This patch adds an option to skip the registration of LCD stdio output for
boards that want to show different text on LCD than on serial output (or
the active stdout selected by the environment variable).

[U-Boot] [PATCH 002/159] arm: mx6: Reduce SPL malloc pool size

[Lin Huang]

From: Marek Vasut <marex@denx.de>

Using 50 MiB malloc pool in SPL is nonsense. Since the caches are not
enabled in SPL, it takes 2 seconds to init the pool and has no obvious
benefit. Reduce the size to 1 MiB.

Marek's patch was already accepted and it is mainline. Which is the
reason to post it again ?
