2011-07-29multiboot: Fix bss segment supportGöran Weinholt1-5/+9
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.

2011-07-23multiboot: Support commas in module parametersAdam Lackorzynski1-9/+9
Support commas in the parameter list of multiboot modules as well as for the kernel command line, by using double commas (via get_opt_value()).

2011-06-03multiboot: set boot_device to first partitionArun Thomas1-1/+1
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.

2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno1-2/+2
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.
