* x86: Fix support for booting bzImageGraeme Russ2010-05-06-32/+95
| | | | | | | | | | | Add support for newer (up to 2.6.33) kernels Add zboot command which takes the address of a bzImage as its first argument and (optionally) the size of the bzImage as the second argument (the second argument is needed for older kernels which do not include the bzImage size in the header) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
* x86: Provide weak PC/AT compatibility setup functionGraeme Russ2010-05-06-0/+7
| | | | | | | | | | It is possibly to setup x86 boards to use non-PC/AT configurations. For example, the sc520 is an x86 CPU with PC/AT and non-PC/AT peripherals. This function allows the board to set itself up for maximum PC/AT compatibility just before booting the Linux kernel (the Linux kernel 'just works' if everything is PC/AT compliant) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

* x86: Pass relocation offset into Global DataGraeme Russ2010-05-06-27/+36
| | | | | | | In order to locate the 16-bit BIOS code, we need to know the reloaction offset. Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
* x86: Fix do_go_exec()Graeme Russ2010-05-06-4/+4
| | | | | | | This was broken a long time ago by a49864593e083a5d0779fb9ca98e5a0f2053183d which munged the NIOS and x86 do_go_exec() Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-0/+3579
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
