[U-Boot] [PATCH] ARM: UniPhier: decrease pre-reloc malloc area size

[Masahiro Yamada]

In the current implementation of the boot sequence of UniPhier
platform, 32KB temporary RAM is available before relocation.
The malloc area and the stack shares the 32KB area.

With CONFIG_SYS_MALLOC_F_LEN set to 0x7000 (28KB), only 0x1000 (4KB)
is left for the stack.  In some use cases, the system hangs up
with stack over-flow.

Even with driver-model UART enabled, the malloc area of 0x2000 (8KB)
should be enough.
