2018-01-26microblaze: boot.c: Don't try to find NULL fileAlistair Francis1-1/+1
Previously if no device tree was passed to microblaze_load_kernel() then qemu_find_file() would try to find a NULL pointer. To avoid this put a check around qemu_find_file().

2016-03-04loader: Add data swap option to load-elfPeter Crosthwaite1-2/+2
Some CPUs are of an opposite data-endianness to other components in the system. Sometimes elfs have the data sections layed out with this CPU data-endianness accounting for when loaded via the CPU, so byte swaps (relative to other system components) will occur. The leading example, is ARM's BE32 mode, which is is basically LE with address manipulation on half-word and byte accesses to access the hw/byte reversed address. This means that word data is invariant across LE and BE32. This also means that instructions are still LE. The expectation is that the elf will be loaded via the CPU in this endianness scheme, which means the data in the elf is reversed at compile time. As QEMU loads via the system memory directly, rather than the CPU, we need a mechanism to reverse elf data endianness to implement this possibility.

2015-09-25mb: Remove ELF_MACHINE from cpu.hPeter Crosthwaite1-2/+2
The only generic code relying on this is linux-user, but linux-users' default behaviour or setting ELF_MACHINE to ELF_ARCH will handle this. The microblaze bootloader can just pass EM_MICROBLAZE directly, as that is architecture specific code. This removes another architecture specific definition from the global namespace. Cc: Edgar E.

2014-11-03hw/core/loader: implement address translation in uimage loaderMax Filippov1-1/+2
Such address translation is needed when load address recorded in uImage is a virtual address. When the actual load address is requested, return untranslated address: user that needs the translated address can always apply translation function to it and those that need it untranslated don't need to do the inverse translation. Add translation function pointer and its parameter to uimage_load prototype. Update all existing users. No user-visible functional changes.

2014-05-13microblaze: boot: Don't hack the elf entry pointPeter Crosthwaite1-1/+1
There was some modulo logic to ensure that Microblaze always booted into physical RAM regardless of the elf entry. Removed it, as QEMU should fail gracefully when given a bad elf, rather than attempt to run it. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E.

2013-07-09microblaze: Fix latent bug with default DTB lookupMarkus Armbruster1-14/+13
microblaze_load_kernel() fails to call qemu_find_file(QEMU_FILE_TYPE_BIOS, dtb_filename) when no -machine options are given. This can't normally happen, because -machine option kernel is mandatory for this target. Fix it anyway, by using qemu_get_machine_opts().
