* rom loader: also try filename as-is.Gerd Hoffmann2009-10-121-2/+1

* rom loader: fix sparc -kernel boot.Gerd Hoffmann2009-10-121-6/+32
| | | | | | | | | | | | | | | | | | | | | | | | Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.

* Reorganize option rom (+linux kernel) loading.Gerd Hoffmann2009-10-061-57/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-15/+15
| | | | | | | | | | | | 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.

* Compile loader only onceBlue Swirl2009-09-201-0/+546
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.
