ARM: footbridge: remove custom DMA address handling

2022-09-15T13:59:16Z

Footbridge is the last Arm platform that has its own __virt_to_bus()/__bus_to_virt()/phys_to_dma()/dma_to_phys() abstraction, but this is just a simple offset now. For PCI devices, the offset that is programmed into the PCI bridge must also be set in each device using dma_direct_set_offset(). As Arm does not have a pcibios_bus_add_device() helper yet, just use a bus notifier for this. For the ISA DMA, drivers now pass a non-translated physical address into set_dma_addr(), so they have to be converted back with the corresponding isa_bus_to_virt() function and then into the correct bus address with the offset using the isa_dma_dev.

ARM: footbridge: remove addin mode

2022-09-09T15:14:16Z

This does not appear to have been used in many years, we can kill off some of the uglier code. Among other things, it avoids a randconfig issue when both modes are disabled: arch/arm/mach-footbridge/common.c:149:24: error: 'ebsa285_host_io_desc' defined but not used [-Werror=unused-variable] 149 | static struct map_desc ebsa285_host_io_desc[] __initdata = { | ^~~~~~~~~~~~~~~~~~~~ arch/arm/mach-footbridge/common.c:136:24: error: 'fb_common_io_desc' defined but not used [-Werror=unused-variable] 136 | static struct map_desc fb_common_io_desc[] __initdata = { | ^~~~~~~~~~~~~~~~~ The recently added phys_to_dma() functions are now trivial and could probably be removed again as a follow-up, if anyone knows how.

[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach

2008-08-07T08:55:48Z

This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King

[ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead

2008-08-07T08:40:08Z

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King

[ARM] move include/asm-arm to arch/arm/include/asm

2008-08-02T20:32:35Z

Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King
