Save memory allocation in the elf loader
The current elf loader uses too much memory. For example, I have aexecutable with a bss section of 400 MB and I set the ram size to 512MB. Qemu uses about 780MB of RAM (which is fine), but there's a peak at1.6 GB during initialization (this is not fine)....
HMP: add QDict to info callback handler
This patch change all info call back function to takeadditional QDict * parameter, which allow those commandtake parameter. Now it is set to NULL at default case.

Rename target_phys_addr_t to hwaddr
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes arereserved) and its purpose doesn't match the name (most target_phys_addr_taddresses are not target specific). Replace it with a finger-friendly,...
use an uint64_t for the max_sz parameter in load_image_targphys
Allow load_image_targphys to load files on systems with more than 2G ofemulated memory by changing the max_sz parameter from an int to anuint64_t.

loader: Fix read_targphys() to behave when read() fails
Happily passes (size_t)-1 to rom_add_blob_fixed(), which promptly diesattempting to malloc that much. Spotted by Coverity.
Bonus fix for ROMs larger than INT_MAX bytes: return ssize_t insteadof int. Bug can't bite, because the only user load_aout() limits ROM...

load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physicaladdresses. Currently the only possibility is to add a value to theaddresses.
This patch replaces the addend argument by and a translation function...
Remove conditional rom loading support
Commit c2039bd0ffce8807e0eaac55254fde790825fa92 made rom loadingautomatic for non-PC architectures. Remove now mostly unusedconditional rom loading support.

roms: minor fixes and cleanups.
Changes: - Drop extra file argument from rom_add_file(). - Drop fw_dir check in do_info_roms, we allways have a dir name. - code style fixes.

roms: rework rom loading via fw
This patch changes the way rom loading via fw_cfg is handled.Instead of having pc_init1() call a function which passed allroms to the firmware config we simply pass a pointer to fw_cfgto the rom loader.
Advantage: loading roms via firmware works also for devices which...
roms: use new fw_cfg file xfer support.
roms: use fw_cfg for vgabios and option rom loading, additionally todeploying them the traditional way (copy to 0xc0000 -> 0xe0000 range).
roms: remove option rom packing logic
Now that we load the option roms via fw_cfg, we can stop copyingthem to the 0xc000 -> 0xe000. The patch does just that.
Also the rom loader gets simplified as all remaining users of therom loader load the bits at a fixed address so the packing and...
Introduce rom_copy
We have several rom helpers currently, but none of them can get uscode that spans several roms into a pointer.
This patch introduces a function that copies over rom contents.

The rom_add_vga() and rom_add_option() macros are transformed intofunctions. They look at the new rom_enable_driver_roms variableand only do something if it is set to non-zero, making vga+option romloading runtime option. pc_init() sets rom_enable_driver_roms to 1....
