ARM: keystone2: rename init_meminfo to pv_fixup

2015-06-01T22:45:56+00:00

The init_meminfo() method is not about initialising meminfo - it's about fixing up the physical to virtual translation so that we use a different physical address space, possibly above the 4GB physical address space. Therefore, the name "init_meminfo()" is confusing. Rename it to pv_fixup() instead. Acked-by: Santosh Shilimkar Tested-by: Murali Karicheri Signed-off-by: Russell King

ARM: keystone2: move update of the phys-to-virt constants into generic code

2015-06-01T22:45:50+00:00

Make the init_meminfo function return the offset to be applied to the phys-to-virt translation constants. This allows us to move the update into generic code, along with the requirements for this update. This avoids platforms having to know the details of the phys-to-virt translation support.

arm: Add devicetree fixup machine function

2014-07-30T03:26:49+00:00

Commit 1c2f87c22566cd057bc8cde10c37ae9da1a1bb76 (ARM: 8025/1: Get rid of meminfo) dropped the upper bound on the number of memory banks that can be added as there was no technical need in the kernel. It turns out though, some bootloaders (specifically the arndale-octa exynos boards) may pass invalid memory information and rely on the kernel to not parse this data. This is a bug in the bootloader but we still need to work around this. Work around this by introducing a dt_fixup function. This function gets called before the flattened devicetree is scanned for memory and the like. In this fixup function for exynos, limit the maximum number of memory regions in the devicetree.

ARM: 8025/1: Get rid of meminfo

2014-06-01T00:17:12+00:00

memblock is now fully integrated into the kernel and is the prefered method for tracking memory. Rather than reinvent the wheel with meminfo, migrate to using memblock directly instead of meminfo as an intermediate.

ARM: l2c: add platform independent core L2 cache OF initialisation

2014-05-29T23:49:00+00:00

Add a hook into the core ARM code to perform L2 cache initialisation in a platform independent manner. Platforms still get to indicate their auxiliary control register values and mask, but the initialisation call will now be made from generic code. Signed-off-by: Russell King

ARM: mm: Recreate kernel mappings in early_paging_init()

2013-10-11T00:28:19+00:00

This patch adds a step in the init sequence, in order to recreate the kernel code/data page table mappings prior to full paging initialization. This is necessary on LPAE systems that run out of a physical address space outside the 4G limit. On these systems, this implementation provides a machine descriptor hook that allows the PHYS_OFFSET to be overridden in a machine specific fashion.

ARM: use phys_addr_t for DMA zone sizes

2013-08-13T20:52:33+00:00

In order to specify a DMA zone size of 4GB on LPAE systems, the sizes need to be 64-bit. So make machine_desc.dma_zone_size and arm_dma_zone_size be phys_addr_t instead of unsigned long. Signed-off-by: Rob Herring

ARM: constify machine_desc structure uses

2013-07-26T13:55:59+00:00

struct machine_desc records are defined everywhere as a 'const' structure, but unfortuantely it loses its const-ness through the use of linker magic - the symbols which surround the section are not declared const so it becomes possible not to use 'const' for pointers to these const structures. Let's fix this oversight - all pointers to these structures should be marked const too. Signed-off-by: Russell King
