ARM: at91: fix ordering of SRAM and PM initialization The PM initialization needs internal SRAM for allocating a gen_pool and use it to store its PM code. So we need to have of_platform_populate() before this code. Suggested-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

ARM: at91: mark const init data with __initconst instead of __initdata As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.
