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

2008-08-02T20:32:35+00:00

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

iop: unconditionally initialize the ATU on platforms known to be 'hosts'

2008-03-26T19:33:41+00:00

Platforms like iq80321 and iq80331 which may be host-bus-adapters require 'iop3xx_init_atu=y' to be specified on the kernel command line. Signed-off-by: Dan Williams

[ARM] Fix iop3xx macro

2007-11-05T09:40:27+00:00

Macro arguments used in expressions should have parens. This avoids warnings such as: drivers/serial/8250.c:1951: warning: suggest parentheses around arithmetic in operand of | Acked-by: Dan Williams Acked-by: Lennert Buytenhek Signed-off-by: Russell King

[ARM] 4495/1: iop: combined watchdog timer driver for iop3xx and iop13xx

2007-07-20T08:35:42+00:00

In order for this driver to be shared across the iop architectures the iop3xx and iop13xx header files are modified to present a common interface for the iop_wdt driver. Details: * iop13xx supports disabling the timer while iop3xx does not. This requires a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code. * The heartbeat interval is derived from the internal bus clock rate, so this this patch also exports the tick rate to the iop_wdt driver.

iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driver

2007-07-13T15:06:19+00:00

Adds the platform device definitions and the architecture specific support routines (i.e. register initialization and descriptor formats) for the iop-adma driver. Changelog: * add support for > 1k zero sum buffer sizes * added dma/aau platform devices to iq80321 and iq80332 setup * fixed the calculation in iop_desc_is_aligned * support xor buffer sizes larger than 16MB * fix places where software descriptors are assumed to be contiguous, only hardware descriptors are contiguous for up to a PAGE_SIZE buffer size * convert to async_tx * add interrupt support * add platform devices for 80219 boards * do not call platform register macros in driver code * remove switch() statements for compatible register offsets/layouts * change over to bitmap based capabilities * remove unnecessary ARM assembly statement * checkpatch.pl fixes * gpl v2 only correction * phys move to dma_async_tx_descriptor Cc: Russell King Signed-off-by: Dan Williams

[ARM] iop: add missing parens in macro

[ARM] 4348/4: iop3xx: Give Linux control over PCI initialization

2007-05-03T13:02:48+00:00

Currently the iop3xx platform support code assumes that RedBoot is the bootloader and has already initialized the ATU. Linux should handle this initialization for three reasons: 1/ The memory map that RedBoot sets up is not optimal (page_to_dma and virt_to_phys return different addresses). The effect of this is that using the dma mapping API for the internal bus dma units generates pci bus addresses that are incorrect for the internal bus. 2/ Not all iop platforms use RedBoot 3/ If the ATU is already initialized it indicates that the iop is an add-in card in another host, it does not own the PCI bus, and should not be re-initialized. Changelog: * rather than change nr_controllers to zero, simply do not call pci_common_init Cc: Lennert Buytenhek Signed-off-by: Dan Williams Signed-off-by: Russell King

[ARM] 4187/1: iop: unify time implementation across iop32x, iop33x, and iop13xx

2007-02-17T15:05:40+00:00

* architecture specific details are handled in asm/arch/time.h * ARCH_IOP13XX now selects PLAT_IOP * as suggested by Lennert use ifdef CONFIG_XSCALE to skip the cp_wait on XSC3 Signed-off-by: Dan Williams Signed-off-by: Russell King

[ARM] 4186/1: iop: remove cp6_enable/disable routines

[ARM] 4184/1: iop: cp6 access handler (undef_hook)

2007-02-14T15:21:24+00:00

Enable svc access to cp6 via an undefined instruction hook. Do not enable access for usr code. This patch also makes iop13xx select PLAT_IOP, this requires a small change to drivers/i2c/busses/i2c-iop3xx.c. Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop Per Nicolas Pitre's note, the cp_wait is skipped since the latency to return to the faulting function is longer than cp_wait.
