2008-05-26sh: Drop broken URAM support on SH7723.Paul Mundt1-6/+0
This was copied over from the previous MobileR bits, which doesn't apply to R2. The URAM block on R2 is recycled for the L2 instead. Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: add probe support for new sh7723 cutMagnus Damm1-0/+1
This patch adds support for sh7723 silicon with a prr value of 0x51. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: fix VPU interrupt vector for sh7723Magnus Damm1-1/+1
This patch fixes a VPU vector typo for sh7723. The correct value is 0x980, the same as for sh7722. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: fix USBF resource for sh7722Magnus Damm1-1/+1
The USBF function on sh7722 is currently not working with the m66592_udc driver. The driver is using platform_get_resource_byname() so my commit a0d29798e568116aa6c32aef7bab2d9e620c88ad broke sh7722 support. The long term fix is to replace platform_get_resource_byname() in the driver with platform_get_resource(), but this helps until that happens.

2008-05-19sh: Fix up restorer in debug_trap exception return path.Paul Mundt1-6/+5
There are a few different types of debug trap exceptions, though now that they are all going through a special jump table, the restorer needs to be unified as well. Presently this is falling through the ret_from_fork path, which more or less does the right thing on SH-3/4 whilst being completely unsuitable on MMU-less targets. Ultimately what we want here is a branch through the platform's restore_all directly, without worrying about the retval being clobbered. We can accomplish that through a branch to __restore_all directly, so switch it so we come back from the jump table and branch to the restorer. This fixes up a recursion in the nommu WARN_ON() path, as well as some other userspace nastiness where said recursion caused serious stack corruption. Signed-off-by: Paul Mundt <[email protected]>
2008-05-19sh: Make is_valid_bugaddr() more intelligent on nommu.Paul Mundt1-1/+9
Currently is_valid_bugaddr() is true for anything >= PAGE_OFFSET, which happens to be 0 on nommu configurations. Make this a bit smarter by just reading in the opcode and comparing it against the trap type that we already know. Follows the logic from avr32. Signed-off-by: Paul Mundt <[email protected]>

2008-05-16sh: Fix up thread info pointer in syscall_badsys resume path.Hideo Saito1-0/+1
Entry to resume_userspace expects r8 to contain current_thread_info, which happens in all paths except for syscall_badsys, where r8 was being inadvertently trampled. Reload it before the branch. Signed-off-by: Hideo Saito <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-16sh: disable initrd defaults in .empty_zero_page.Paul Mundt1-2/+2
When using initramfs on systems that don't explicitly clear LOADER_TYPE, unpack_to_rootfs() tramples tramples the range with the defaults taken out of .empty_zero_page. This causes kernels with valid initramfs images to bail out with crc or gzip magic mismatch errors after the second unpack takes place on certain platform configurations. Signed-off-by: Paul Mundt <[email protected]>
2008-05-16sh: display boot params by default on entry.Paul Mundt1-0/+11
Some kernel and boot loader configurations tweak the .empty_zero_page settings, while others do not. Print the values out on entry as a debugging aid. Signed-off-by: Paul Mundt <[email protected]>
2008-05-14lib: create common ascii hex arrayHarvey Harrison1-8/+0
Add a common hex array in hexdump.c so everyone can use it. Add a common hi/lo helper to avoid the shifting masking that is done to get the upper and lower nibbles of a byte value. Pull the pack_hex_byte helper from kgdb as it is opencoded many places in the tree that will be consolidated.

2008-05-08sh: no high level trigger on some sh3 cpusMagnus Damm1-0/+5
The processor models sh7706, sh7707 and sh7709 don't support high level trigger sense configuration. And the intc code looks like crap these days so what's the difference. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-08sh: clean up sh7710 and sh7720 intc tablesMagnus Damm2-8/+1
Clean up the intc tables by removing unneeded #ifdefs. The vector list is what selects which interrupt sources that should be added, having unsupported bitfields listed is ok as long as the vector is excluded from the list.

2008-05-08sh: add interrupt ack code to sh3Magnus Damm2-7/+87

2008-05-08sh: unify external irq pin code for sh3Magnus Damm6-94/+75
This patch unifies the sh3 external irq pin code. It buys us some savings with reduced code redundancy, but the main feature with this change is irq sense selection support for all sh3 processors. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2008-05-03unified (weak) sys_pipe implementationUlrich Drepper1-17/+0
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2008-04-18sh: Fix up L2 cache probe.Paul Mundt1-0/+6
SH7723 is the first hard silicon to implement the L2, and unsurprisingly, does the precise inverse of what the specification alleges. XOR the URAM/L2 size bits to get back in line with the existing parsing logic. Signed-off-by: Paul Mundt <[email protected]>
