      [ARM] remove a common set of __virt_to_bus definitions · b5ee9002
      由 Nicolas Pitre 提交于 
      Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

      [ARM] 5316/1: AT91: oops (regression) fix on gpio irq · 085eefb5
      由 David Brownell 提交于 
      From: David Brownell <dbrownell@users.sourceforge.net>

The "5298/1: Drop desc_handle_irq()" patch went overboard
and deleted an essential line of code, causing all AT91
GPIO interrupts to oops (in irq).  Trimmed example:

Unable to handle kernel NULL pointer dereference at virtual address 000000c4
...
PC is at gpio_irq_handler+0x78/0xd0
LR is at gpio_irq_handler+0x38/0xd0

      Fix rename of at91_nand -> atmel_nand · f6ed6f78
      由 Pieter du Preez 提交于 
      Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.

I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.

This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.

Before this patch:

$ git-ls-files |xargs grep atmel_nand |wc -l
105
$ git-ls-files |xargs grep at91_nand |wc -l
4
$ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l
8
$ git-ls-files |xargs grep MTD_NAND_AT91 |wc -l
47

After this patch:

$ git-ls-files |xargs grep atmel_nand |wc -l
109
$ git-ls-files |xargs grep at91_nand |wc -l
0
$ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l
55
$ git-ls-files |xargs grep MTD_NAND_AT91 |wc -l
0
