2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno
A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.

2010-01-03loader: don't call realloc(non_null, 0) when no symbols are presentAurelien Jarno
According to C99, realloc(non_null, 0) != free(non_null), that's why it is forbidden in QEMU. When there are no symbols, nsyms equals to 0. Free the syms structure and set it to NULL instead of reallocating it with a size of 0. This fixes -kernel with stripped kernels.

2009-10-06Reorganize option rom (+linux kernel) loading.Gerd Hoffmann
This patch adds infrastructure to maintain memory regions which must be restored on reset. That includes roms (vga bios and option roms on pc), but is also used when loading linux kernels directly. Features: - loading files is supported. - passing blobs is supported. - target address range is supported (for optionrom area). - fixed target memory address is supported (linux kernel). New in v2: - writes to ROM are done only at initial boot. - also handle aout and uimage loaders. - drop unused fread_targphys() function. The final memory layout is created once all memory regions are registered. The option roms get addresses assigned and the registered regions are checked against overlaps. Finally all data is copyed to the guest memory. Advantages: (1) Filling memory on initial boot and on reset takes the same code path, making reset more robust. (2) The need to keep track of the option rom load address is gone. (3) Due to (2) option roms can be loaded outside pc_init(). This allows to move the pxe rom loading into the nic drivers for example. Additional bonus: There is a 'info roms' monitor command now. The patch also switches over pc.c and removes the option_rom_setup_reset() and load_option_rom() functions.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-20Compile loader only onceBlue Swirl
Callers must pass ELF machine, byte swapping and symbol LSB clearing information to ELF loader. A.out loader needs page size information, pass that too as a parameter. Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw. Adjust callers. Also use target_phys_addr_t instead of target_ulong for addresses: loader addresses aren't virtual.
