We are still using custom SRAM code for some SoCs and are not marking the PM code mapped to SRAM as read-only and executable after we're done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping at address" warning. Let's fix this issue the same way as commit 728bbe75c82f ("misc: sram: Introduce support code for protect-exec sram type") is doing for drivers/misc/sram-exec.c. On omap3, we need to restore SRAM when returning from off mode after idle, so init time configuration is not enough. And as we no longer have users for omap_sram_push_address() we can make it static while at it. Note that eventually we should be using sram-exec.c for all SoCs.

This patch fixes a bootproblem with the Bananapi M2 board. Since there are some regulators missing we add them right now. Those values come from the schematic, below you can find a small overview: * reg_aldo1: 3,3V, powers the wifi * reg_aldo2: 2,5V, powers the IO of the RTL8211E * reg_aldo3: 3,3V, powers the audio * reg_dldo1: 3,0V, powers the RTL8211E * reg_dldo2: 2,8V, powers the analog part of the csi * reg_dldo3: 3,3V, powers misc * reg_eldo1: 1,8V, powers the csi * reg_ldo_io1:1,8V, powers the gpio * reg_dc5ldo: needs to be always on This patch updates also the vmmc-supply properties on the mmc0 and mmc2 node to use the allready existent regulators.

When trying to use the driver (e.g. aplay *.wav), the 4MiB DMA buffer will get mmapp'ed in 16KiB chunks. But this fails with the 2nd 16KiB area, as the page offset is outside of the VMA range (size), which is currently used as size parameter in snd_pcm_lib_default_mmap(). By using the DMA buffer size (dma_bytes) instead, the complete DMA buffer can be mmapp'ed and the issue is fixed. This issue was detected on an ARM platform (TI AM57xx) using the RME HDSP MADI PCIe soundcard.

BAU uses the old alloc_initr_gate90 method to setup its interrupt. This fails silently as the BAU vector is in the range of APIC vectors that are registered to the spurious interrupt handler. As a consequence BAU broadcasts are not handled, and the broadcast source CPU hangs. Update BAU to use new idt structure.
