Subject: [U-Boot] [PATCH] ARM: crt0: Pass malloc base address
Date: Wed, 11 Nov 2015 18:23:17 -0200	[thread overview]
Message-ID: <1447273397-22833-1-git-send-email-festevam@gmail.com> (raw)

From: Fabio Estevam <fabio.estevam@freescale.com>

Commit 5ba534d247d418 ("arm: Switch 32-bit ARM to using generic global_data
setup") causes malloc() to fail in SPL.

The reason is that the GD_MALLOC_BASE is not passed anymore.

Restore the code that passes malloc base so that we can have
malloc working in SPL code again.
