| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iq80310 mtd map driver depends on ARCH_IQ80310, which isn't defined anywhere in the tree (as we don't have 80310 support), and furthermore, everything the driver does can be done with physmap instead.

| * | [MTD] Unlock NOR flash automatically where necessaryHåvard Skinnemoen2006-09-223-0/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is always locked after power-up, so all sectors need to be unlocked before it is usable. If this flag is set, and the chip provides an unlock() operation, mtd_add_device will unlock the whole MTD device if it's writeable. This means that non-writeable partitions will stay locked. Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work as expected.

| | | | | | | | | | | | | | | | | | | | On detection of an EEH error, some Power4 systems seem to occasionally want to be reset twice before they report themselves as fully recovered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Noticed that the U3_*CFA macros have some typos: #define U3_HT_CFA0(devfn, off) \ ((((unsigned long)devfn) << 8) | offset) (refers to offset rather than off) #define U3_AGP_CFA0(devfn, off) \ ((1 << (unsigned long)PCI_SLOT(dev_fn)) \ | (((unsigned long)PCI_FUNC(dev_fn)) << 8) \ (refers to dev_fn rather than devfn) Things happen to work, but there doesn't seem to be any reason these shouldn't be functions.

| * [POWERPC] Maple U3 HT - reject inappropriate config space accessNathan Lynch2006-09-221-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a PCI-X mode 2 capable device behind the HT<->PCI-X bridge, the pci core decides that the device has the extended 4K config space, even though the bus is not operating in mode 2. This is because the u3_ht pci ops silently accept offsets greater than 255 but use only the 8 least significant bits, which means reading at offset 0x100 gets the data at offset 0x0, and causes confusion for lspci. Reject accesses to configuration space offsets greater than 255. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [POWERPC] powerpc: fix building gdb against asm/ptrace.hArnd Bergmann2006-09-221-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ulrich Weigand found a bug with the current version of the asm-powerpc/ptrace.h that prevents building at least the SPU target version of gdb, since some ptrace opcodes are not defined. The problem seems to have originated in the merging of 32 and 64 bit versions of that file, the problem is that some opcodes are only valid on 64 bit kernels, but are also used by 32 bit programs, so they can't depends on the __powerpc64__ symbol.

| | | | | | | | | | | | | | | | | | | | | | | | Update to the PowerPC PCI error recovery code. Add code to enable MMIO if a device driver reports that it is capable of recovering on its own. One anticipated use of this having a device driver enable MMIO so that it can take a register dump, which might then be followed by the device driver requesting a full reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.

On systems that happen to be configured for both ttyS0 and hvc0 console, this will keep flooding the console output. This is most likely to happen with systems booted between with and without hypervisor from the same filesystem. Let's just remove it. When it's really needed (i.e. when the open fails and someone is trying to debug it), noone will see the output anyway. And init will report the opens failing in due time through the syslog.
