Subject: [U-Boot] [PATCH v2 4/5] microblaze: Do not use CONFIG_SYS_GENERIC_GLOBAL_DATA
Date: Mon,  2 Feb 2015 16:46:18 +0100	[thread overview]
Message-ID: <2ec36ee6b2b040e5852d98499f3460a648da7f24.1422891972.git.michal.simek@xilinx.com> (raw)
In-Reply-To: <615eec5129d03589f4d10a356a31b52ac4483db0.1422891972.git.michal.simek@xilinx.com>

Because it is not compatible with DM where
malloc_base has to be available early and init
has to be done in ASM.

Signed-off-by: Michal Simek <michal.simek@xilinx.com>

Changes in v2:
- New patch in the series

Moving it to C code is also possible.
