Subject: [PATCH 05/28] ARM: at91: replace at91sam9_ddrsdr.h with at91bootstrap's at91_ddrsdrc.h
Date: Wed,  1 Jul 2020 07:23:17 +0200	[thread overview]
Message-ID: <20200701052340.9462-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200701052340.9462-1-a.fatoum@pengutronix.de>

Instead of adding missing definitions to the existing at91sam9_ddrsdr.h
and adapting the incoming DDRAM initialization code from at91bootstrap,
just replace the lightly used existing header with:
https://github.com/linux4sam/at91bootstrap/blob/v3.8.12/include/arch/at91_ddrsdrc.h

For easier comprehension, the replacement is done in three steps:
This last step copies the memory size querying functions from at91sam9_ddrsdr.h
to at91_ddrsdrc.h, then deletes it and fixes all references.
