[PATCH] ARM: at91: move sdramc/ddrsdr header to include/soc/at91

Alexandre Belloni alexandre.belloni at free-electrons.com
Fri Nov 7 12:58:21 PST 2014


Move the (DDR) SDRAM controller headers to include/soc/at91 to remove the
dependency on mach/ headers from the at91-reset driver.

Signed-off-by: Alexandre Belloni <alexandre.belloni at free-electrons.com>
---
As my previous attempts were not popular, solve the mach/ headers issue by
simply moving them. I'll get back to better driver separation when it will be
possible to map the SRAM as executable memory.
