Subject: [PATCH] ARM: Make memory known to lowlevel code
Date: Wed, 17 Oct 2012 23:03:09 +0200	[thread overview]
Message-ID: <1350507817-7819-1-git-send-email-s.hauer@pengutronix.de> (raw)

Memory is a precious resource and should be known early. This series
adds a new entry point for ARM which is passed the SDRAM region used
for barebox. This allows us to setup the stack and malloc space
according to the RAM we have and get rid of the values from Kconfig.
Later with relocatable binary support it will allow us to find a
suitable base for barebox.
With the new entry point it is also possible for the lowlevel code
to pass a pointer on to barebox which can be retrieved later. This
way data from an earlier loader can be passed on.
It is not necessary to pass the whole SDRAM to the entry point (which
wouldn't be possible anyway when there are multiple memory banks).
It instead is enough to pass the memory barebox should use for itself.
i.MX gets functions to read back the SDRAM size from the controller.
Atmel and Samsung also have such a function, but these are not used
by every board, I didn't change that. Other boards have different
possible SDRAM sizes, I passed the minimum amount to the barebox
entry.
