* ARM1136: Fix cache range checksBenoît Thébaudeau2012-07-21-3/+3
| | | | | | | | | | | | | | bad_cache_range actually returned true if the range was OK, but it was used according to its name, which resulted in all valid dcache range invalidate/flush operations being dropped. Hence, most DMA transfers resulted in garbage data. This patch renames this function according to what it does, and it fixes the interpretation of its return value by other functions. The chosen naming is the same as for ARM926EJ-S in order to be consistent.

* ARM: lib: Remove CONFIG_ARCH_CPU_INIT dependencyFabio Estevam2012-07-20-2/+8
| | | | | | | | | | | | Create a weak-aliased arch_cpu_init, so that we can get rid of CONFIG_ARCH_CPU_INIT and always call arch_cpu_init. This way we do not need to define CONFIG_ARCH_CPU_INIT in every board file, since arch_cpu_init() is supposed to handle common CPU level code.

* ARM: OMAP4: PANDA: Add rest of the USB module pads to essentialsSRICHARAN R2012-07-20-22/+22
| | | | | | | | | | | | | | | | In commit 1a89a217f5c5ab3645c80c1247e8911a8b5ad491 we moved most of the required pads and mux data for USB to the essential list so that later on we could NOT enable anything that wasn't essential unless otherwise configured. This was however missing a few pandaboard-specific parts which left for example USB ethernet non-functional. Tested this on OMAP4430 ES2.2, OMAP4460 ES1.1 PANDA boards.

| * usb_storage: fix ehci driver max transfer sizeStefan Herbrechtsmeier2012-07-18-17/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage: Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in usb_storage as it wrongly assumes that every transfer can use 4096 bytes per qt_buffer. This is wrong if the start address of the data is not page aligned to 4096 bytes and leads to 'EHCI timed out on TD' messages because of 'out of buffer pointers' in ehci_td_buffer function. The bug appears during load of a fragmented file and read from or write to an unaligned memory address.

| * ehci-hcd: fix external buffer cache handlingIlya Yanok2012-07-18-9/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Buffer coming from upper layers should be cacheline aligned/padded to perform safe cache operations. For now we don't do bounce buffering so getting unaligned buffer is an upper layer error. We can't check if the buffer is properly padded with current interface so just assume it is (consider changing with in the future). The following changes are done: 1. Remove useless length alignment check. We get actual transfer length not the size of the underlying buffer so it's perfectly valid for it to be unaligned. 2. Move flush_dcache_range() out of while loop or it will flush too much. 3. Don't try to fix buffer address before calling invalidate: if it's unaligned it's an error anyway so let cache subsystem cry about that. 4. Fix end buffer address to be cacheline aligned assuming upper layer reserved enough space. This is potentially dangerous operation so upper layers should be careful about that.

| * ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignmentTom Rini2012-07-18-30/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB spec says that 32 bytes is the minimum required alignment. However on some platforms we have a larger minimum requirement for cache coherency. In those cases, use that value rather than the USB spec minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here as we are not allowed to have tests inside of align(...).
