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.
