Göran Weinholt 6b8273a1b9 multiboot: Fix bss segment support
Multiboot images can specify a bss segment. The boot loader must clear
the memory of the bss and ensure that no modules or structures are
allocated inside it. Several fields are provided in the Multiboot
header that were previously not used properly. The header is now used
to determine how much data should be read from the image and how much
memory should be reserved to the bss segment.

Arun Thomas c83066d4c4 multiboot: set boot_device to first partition
The multiboot info struct's 'boot_device' field has 'part1' set to 0x01, which
maps to the second primary partition. To specify the first primary partition,
'part1' should be set to 0x00, since partition numbers start from zero
according to the multiboot spec.

Jes Sorensen 37a05af069 load_multiboot(): get_image_size() returns int
Do not store return of get_image_size() in a uint32_t as it makes it
impossible to detect error returns from get_image_size.

Isaku Yamahata bd418d90d0 multiboot: compilation fix with DEBUG_MULTIBOOT enabled.
This patch fixes the following compilation errors in multiboot.c
when DEBUG_MULTIBOOT is defined.
Use TARGET_FMT_plx instead of %x for target_phys_addr_t.

Aurelien Jarno 409dbce54b load_elf: replace the address addend by a translation function
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.
