Pull ARM updates from Russell King: - add support for ELF fdpic binaries on both MMU and noMMU platforms - linker script cleanups - support for compressed .data section for XIP images - discard memblock arrays when possible - various cleanups - atomic DMA pool updates - better diagnostics of missing/corrupt device tree - export information to allow userspace kexec tool to place images more inteligently, so that the device tree isn't overwritten by the booting kernel - make early_printk more efficient on semihosted systems - noMMU cleanups - SA1111 PCMCIA update in preparation for further cleanups * 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (38 commits) ARM: 8719/1: NOMMU: work around maybe-uninitialized warning ARM: 8717/2: debug printch/printascii: translate '\n' to "\r\n" not "\n\r" ARM: 8713/1: NOMMU: Support MPU in XIP configuration ARM: 8712/1: NOMMU: Use more MPU regions to cover memory ARM: 8711/1: V7M: Add support for MPU to M-class ARM: 8710/1: Kconfig: Kill CONFIG_VECTORS_BASE ARM: 8709/1: NOMMU: Disallow MPU for XIP ARM: 8708/1: NOMMU: Rework MPU to be mostly done in C ARM: 8707/1: NOMMU: Update MPU accessors to use cp15 helpers ARM: 8706/1: NOMMU: Move out MPU setup in separate module ARM: 8702/1: head-common.S: Clear lr before jumping to start_kernel() ARM: 8705/1: early_printk: use printascii() rather than printch() ARM: 8703/1: debug.S: move hexbuf to a writable section ARM: add additional table to compressed kernel ARM: decompressor: fix BSS size calculation pcmcia: sa1111: remove special sa1111 mmio accessors pcmcia: sa1111: use sa1111_get_irq() to obtain IRQ resources ARM: better diagnostics with missing/corrupt dtb ARM: 8699/1: dma-mapping: Remove init_dma_coherent_pool_size() ARM: 8698/1: dma-mapping: Mark atomic_pool as __ro_after_init ..

help

|
The kernel needs to change the hardware exception vectors.
|
|
In nommu mode, the hardware exception vectors are normally
|
|
placed at address 0x00000000. However, this region may be
|
|
occupied by read-only memory depending on H/W design.
|
|
|
|
If the region contains read-write memory, say 'n' here.
|
|
|
|
If your CPU provides a remap facility which allows the exception
|
|
vectors to be mapped to writable memory, say 'n' here.
|
|
|
|
Otherwise, say 'y' here. In this case, the kernel will require
|
|
external support to redirect the hardware exception vectors to
|
|
the writable versions located at DRAM_BASE.

help
|
|
Some ARM systems without an MMU have instead a Memory Protection
|
|
Unit (MPU) that defines the type and permissions for regions of
|
|
memory.
|
|
|
|
If your CPU has an MPU then you should choose 'y' here unless you
|
|
know that you do not want to use the MPU.
