* microblaze: Do not use _start in vmlinuxMichal Simek2010-08-041-2/+2
| | | | | | | | _start symbol stores physical address where kernel is. Gdb uses this symbol for their purpose that's why we have to rename it. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Allow PAGE_SIZE configurationSteven J. Magnani2010-08-041-6/+6
| | | | | | | | | | Allow developer to configure memory page size at compile time. Larger pages can improve performance on some workloads. Based on PowerPC code. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Quiet section mismatch warningsSteven J. Magnani2010-05-061-1/+2
| | | | | | | | _start is located in .text, which causes mismatch warnings with machine_early_init() and start_kernel() in .init.text. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | The problem was that free_initmem pass to free_initrd_mem got bad aligned __init_begin symbol and free_initrd_mem don't care about __init_end but take PAGE_SIZE instead.

* microblaze: Fix _start symbol to physical addressMichal Simek2009-09-221-0/+1
| | | | | | | | | _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>
* microblaze: Use LOAD_OFFSET macro to get correct LMA for all sectionsMichal Simek2009-09-221-15/+19
| | | | | | | | | | | | | 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>
* microblaze: Cleanup linker script using new linker script macros.Tim Abbott2009-09-211-31/+8
| | | | | | | | | | | | | 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.

* linker script: unify usage of discard definitionTejun Heo2009-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Discarded sections in different archs share some commonality but have considerable differences. This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390. Michal Simek tested microblaze.

* microblaze: include EXIT_TEXT to _stextMichal Simek2009-07-091-2/+2
| | | | | | | | | | | | Microblaze wants to throw out EXIT_TEXT during runtime too. This hasn't caused trouble till now because the linker script didn't discard EXIT_TEXT and it ended up in its default output section. As discard definition is about to be unified, include EXIT_TEXT into _stext explicitly and while at it replace explicit exitcall definition to EXIT_CALL.

* linker script: throw away .discard sectionTejun Heo2009-06-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86 throws away .discard section but no other archs do. Also, .discard is not thrown away while linking modules. Make every arch and module linking throw it away. This will be used to define dummy variables for percpu declarations and definitions. This patch is based on Ivan Kokshaysky's alpha percpu patch.
