| * [ARM] kirkwood: fix PCI I/O port assignmentLennert Buytenhek2009-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of allocating PCI devices I/O port bus addresses from the 000xxxxx I/O port range as intended, due to a bus versus physical address mixup, the Kirkwood PCIe handling code inadvertently allocated I/O port bus addresses from the f20xxxxx address range (which is the physical address range of the PCIe I/O mapping window), but then direct all I/O port accesses to bus addresses 000xxxxx, which would then not be decoded at all. Fix this by setting the base address of the PCIe I/O space struct resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses offsetted by the former instead of the latter. (The suggested fix of directing I/O port accesses from the host to bus addresses f20xxxxx instead has the problem that assigning full 32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI devices, as not all PCI devices implement full 32 bit BAR registers for I/O ports. We should really try to allocate I/O port bus addresses that fit in 16 bits.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: Nicolas Pitre <nico@marvell.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mapping the same memory using two different attributes (memory type, shareability, cacheability) is unpredictable. During boot, we encounter a situation when we're updating the kernel's page tables which can lead to dirty cache lines existing in the cache which are subsequently missed. This causes stack corruption, and therefore a crash. Therefore, ensure that the shared and cacheability settings matches the configuration that will be used later; this together with the restriction in early_cachepolicy() ensures that we won't create a mismatch during boot.

If PER goes idle/inactive independently of CORE, for UART3 to wakeup it must have its wakeup enable bits setup in PM_WKEN_PER. This patch enables these bits. The reason it works when PER and CORE work together is because when CORE goes inactive/retention, the IOPAD wakeups are enabled and trigger UART3 wakeup. Without this patch, when the UART inactivity timer fires for UART3, its clocks are disabled and it's unable to wakeup so will be unusable until PER is awoken by another source. Another way of testing is by keeping CORE on during suspend but allowing PER to hit retention # echo 3 > /debug/pm_debug/core_pwrdm/suspend then enter suspend # echo mem > /sys/power/state Without this patch, UART3 will be unable to wakeup the system.

| * | omap1: Fix DSP public peripherals support for ams-deltaJanusz Krzysztofik2009-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?) machines as long as old dspgateway code were present in the l-o tree. For several months it is no longer included, breaking support for McBSP1 based audio on Amstrad Delta, for example. This patch, derived from the old dspgateway code, corrects the problem for the board by simply taking the DSP out of reset state, I guess. That way, things should not break when a new dsp code is added to the tree, and the change can be reverted then. If there are any reports on McBSP1 or other DSP public peripherals not working for other OMAP1 machines (I've not heard of any for now), I can prepare a more general patch providing an extra include file with a helper function defined.

| * | omap1: Fix redundant UARTs pin muxing that can break other hardware supportJanusz Krzysztofik2009-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart and OMAP_TAG_UART. This works for mach-omap2, but causes issues on mach-omap1 for some boards as the mach-omap1 serial.c was muxing pins based on the enabled_uart flag for 15xx. Fix this by muxing pins in board-*.c files for the 15xx boards for the uart ports that had enabled_uart flag set before the commit above. Tested on Amsdtrad Delta only. Note that in the future we should add support for powering down the uarts with a timer like mach-omap2/serial.c does. Otherwise the enabled uarts will be blocking retention-while-idle.
