* Don't try to guess the size of a disk if its size value is already givenJuergen Beisert2010-10-111-1/+1
| | | | | | | | | | | | | | | | | Guessing the size of an attached harddisk (access via x86 BIOS) was needed due to the fact, barebox can't query this information from the BIOS easily. But with the SD/MMC cards, there will be a second user of the generic disk handling routines. And with this media it is very easy to know its size. This patch provides a workaround to keep the guessing feature if the size of the registered disk is 0. If it is not 0, the given value will be used instead. Note: This is in preparation to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: use id as -1 for auto assigned idJean-Christophe PLAGNIOL-VILLARD2010-09-201-0/+3
| | | | | | | | before if you specify id = 0 the next available id will be taken otherwise fail if already registered now as in linux we use -1 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* configs: use new savedefconfig format as in linuxJean-Christophe PLAGNIOL-VILLARD2010-09-171-155/+0
| | | | | | | this will reduce and simplify defconfigs maintainance it will also save some disk space Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* move boards to arch/<architecure>/boardsJean-Christophe PLAGNIOL-VILLARD2010-07-238-2/+247
| | | | | | | | | | | | this will allow each arch to handle the boards more simply and depending on there need the env var BOARD will refer to the current board dirent for sandbox as we have only one board the board dirent is arch/sandbox/board Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add a special command to load and start a bzImage on x86Juergen Beisert2010-01-143-0/+80
| | | | | | | | | Other architectures are supporting the uImage format used by barebox's 'bootm' command. x86 does'nt. So, we need a special command to be able to boot the x86 specific bzImage format. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add a low level disk drive access driverJuergen Beisert2010-01-142-0/+78
| | | | | | | | | This is a low level disk drive communication driver. It uses the real mode BIOS found on most x86 platforms, to read and write sectors. Used by the generic disk driver. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Bring in the time reference for the x86 platformsJuergen Beisert2010-01-142-0/+74

* Add a generic PC platformJuergen Beisert2010-01-141-0/+186
| | | | | | | | | This code adds a generic x86 platform, enabling barebox to act as a bootloader like 'GRUB'. Very minimalistic, yet. Supports only a serial console and is tested with QEMU only. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
