2009-09-24microblaze: Support simpleImage.dts make targetMichal Simek
Instead of remembering to specify DTB= on the make commandline, this commit allows the much friendlier make simpleImage.<dts> where <dts>.dts is expected to be found in arch/microblaze/boot/dts/ The resulting vmlinux, with the compiled DTS linked in, will be copied to boot/simpleImage.<dts> This mirrors the same functionality as on PowerPC, albeit achieving it in a slightly different way. + strip simpleImage file The size of output file is very similar to linux.bin. vmlinux - full elf without fdt blob simpleImage.<dtb name>.unstrip - full elf with fdt blob simpleImage.<dtb name> - stripped elf with fdt blob Add symlink to generic system.dts in platform folder Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-09-22microblaze: Fix _start symbol to physical addressMichal Simek
_start is setup to physical kernel start address. This caused that when you load vmlinux (with MMU kernel) via XMD program counter (pc) is setup correctly and then you can write con and start kernel. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-09-22microblaze: Use LOAD_OFFSET macro to get correct LMA for all sectionsMichal Simek
Currently, vmlinux has LMA==VMA for all sections, which is wrong for MMU kernels. Previous patches in this series defined the LOAD_OFFSET constant, now we make use of it in our link script. Other minor changes in this patch: * brace/indenting cleanup of some sections * put __fdt_* symbols in their own section, and apply LOAD_OFFSET fixup Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-09-22microblaze: Create the LOAD_OFFSET macro used to compute VMA vs LMA offsetsJohn Williams
LOAD_OFFSET is the offset between the physical load address and the kernel's virtual address. It will be used in the upcoming commit to vmlinux.ld.S to make sure that the LMAs of sections in vmlinux are correct. Signed-off-by: John Williams <john.williams@petalogix.com>
2009-09-22microblaze: Copy ppc asm-compat.h for clean handling of constants in asm and CJohn Williams
Provides the ASM_CONST macro for creating asm-safe constants. No users yet, we'll be using it in upcoming page.h commit, for generating the LOAD_OFFSET macro Signed-off-by: John Williams <john.williams@petalogix.com>

2009-09-22microblaze: Save and restore msr in hw exceptionMichal Simek
I thought that this part of code could be removed because just save and restore MSR but any code can't change it. But seems to that any part of code works with this information. This patch solved problem with allocation. Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-09-21microblaze: Cleanup linker script using new linker script macros.Tim Abbott
I wasn't able to further clean up the linker script using the INIT_DATA_SECTION macro because of the FIXME comment for the .init.ramfs section; when that is resolved we should convert microblaze to use INIT_DATA_SECTION.

Ingo points out that I screwed up when merging the 'timers-for-linus' branch in commit a03fdb7612874834d6847107198712d18b5242c7. A bit too much copy-and-pasting caused the end result to have an extraneous 'return' in the middle of an expression. That was obviously bogus. Blush.

2009-09-19USB serial: update the console driverAlan Stern
This patch (as1292) modifies the USB serial console driver, to make it compatible with the recent changes to the USB serial core. The most important change is that serial->disc_mutex now has to be unlocked following a successful call to usb_serial_get_by_index(). Other less notable changes include: Use the requested port number instead of port 0 always. Prevent the serial device from being autosuspended. Use the ASYNCB_INITIALIZED flag bit to indicate when the port hardware has been initialized. In spite of these changes, there's no question that the USB serial console code is still a big hack.

2009-09-19usb-serial: straighten out serial_openAlan Stern
This patch (as1291) removes a bunch of code from serial_open(), things that were rendered unnecessary by earlier patches. A missing spinlock is added to protect port->port.count, which needs to be incremented even if the open fails but not if the tty has gotten a hangup. The test for whether the hardware has been initialized, based on the use count, is replaced by a more transparent test of the ASYNCB_INITIALIZED bit in the port flags.

2009-09-19usb-serial: add missing tests and debug linesAlan Stern
This patch (as1290) adds some missing tests. serial_down() isn't supposed to do anything if the hardware hasn't been initialized, and serial_close() isn't supposed to do anything if the tty has gotten a hangup (because serial_hangup() takes care of shutting down the hardware). The patch also updates and adds a few debugging lines. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-19usb-serial: rename subroutinesAlan Stern
This patch (as1289) renames serial_do_down() to serial_down() and serial_do_free() to serial_release(). It also adds a missing call to tty_shutdown() in serial_release().
