Subject: ARM bootm regression
Date: Fri, 16 Oct 2020 11:49:16 +0300	[thread overview]
Message-ID: <1602838156.455713761@f185.i.mail.ru> (raw)

Hello.

Found a regression in arm/lib32/bootm.c after a patch
"ARM: bootm: make sure we place the kernel in free memory".

The initial memory size for the board is set to 8 MB (before reading the real value from DT),
so the stack, malloc_space, etc. are placed in the initial 8M space.
Then get_kernel_addresses() gets the real SDRAM area (for my board it is 64M),
but decreases this size by the first children size (malloc_space),
so mem_end is incorrect in this case.
