ARM: OMAP2+: Fix SRAM virt to phys translation for save_secure_ram_co…
…ntext [ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ] With the CMA changes from Joonsoo Kim <[email protected]>, it was noticed that n900 stopped booting. After investigating it turned out that n900 save_secure_ram_context does some whacky virtual to physical address translation for the SRAM data address. As we now only have minimal parts of omap3 idle code copied to SRAM, running save_secure_ram_context() in SRAM is not needed. It only gets called on PM init. And it seems there's no need to ever call this from SRAM idle code. So let's just keep save_secure_ram_context() in DDR, and pass it the physical address of the parameters. We can do everything else in omap-secure.c like we already do for other secure code. And since we don't have any documentation, I still have no clue what the values for 0, 1 and 1 for the parameters might be. If somebody has figured it out, please do send a patch to add some comments.
