| * Blackfin: fix up UART status bit handlingMike Frysinger2008-10-23-12/+60
| | | | | | | | | | | | | | | | Some Blackfin UARTs are read-to-clear while others are write-to-clear. This can cause problems when we poll the LSR and then later try and handle any errors detected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: bf561-ezkit: drop redundant codeMike Frysinger2008-10-23-4/+2
| | | | | | | | | | | | Common Blackfin code already announces CPU information. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: bf561-ezkit: drop pointless USB codeMike Frysinger2008-10-23-15/+0
| | | | | | | | | | | | | | The USB/LAN register settings are not actually used/needed in order to drive things from U-Boot, so drop the code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: linker scripts: force start.o and set initcode boundariesMike Frysinger2008-10-23-4/+24
| | | | | | | | | | | | | | | | Make sure that the start.o object is always the first object in our linker script regardless of configuration settings, and add some linker symbols so the ldr utility can properly locate the initcode when generating a LDR.

| * Blackfin: small cpu init optimization while setting interrupt maskMike Frysinger2008-10-23-5/+2
| | | | | | | | | | | | | | Use the sti instruction to set the initial interrupt mask rather than banging on the core IMASK MMR to save both space and time. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: make baud calculation more accurateMike Frysinger2008-10-23-4/+4
| | | | | | | | | | | | | | | | We should use the algorithm in the Linux kernel so that the UART divisor calculation is more accurate. It also fixes problems on some picky UARTs that have sampling anomalies. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: decode hwerrcause/excause when crashingMike Frysinger2008-10-23-2/+40
| | | | | | | | | | | | Having to decode hwerrcause/excause values is a pain, so automate it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: don't bother displaying reboot msg when crashingMike Frysinger2008-10-23-5/+1
| | | | | | | | | | | | | | The hang function already tells you to reboot, so no point in showing it twice. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: enable support for nested interruptsMike Frysinger2008-10-23-4/+10
| | | | | | | | | | | | | | During cpu init, make sure we initialize the CEC properly so that interrupts can fire and be handled while U-Boot is running. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: init NAND before relocating envMike Frysinger2008-10-23-5/+5
| | | | | | | | | | | | | | If booting out of NAND, we need to make sure we initialize it properly before attempting to relocate the environment. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* | 74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cacheDave Liu2008-10-31-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7 mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache This is needed in unlock_ram_in_cache() because it is called from C and will corrupt the small data area anchor that is kept in R2. lock_ram_in_cache() is modified similarly as good coding practice, but is not called from C. Signed-off-by: Nick Spence <nick.spence@freescale.com> also, the r2 is used as global data pointer. Signed-off-by: Dave Liu <daveliu@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Ilko Iliev <iliev@ronetix.at>, the "nand erase clean" command is currently broken, and among other things causes all blocks to be marked bad. This implements it properly using MTD_OOB_AUTO, along with some indentation fixes. Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch defines 1M TLB&LAW size for NAND on MPC8572DS, assigns 0xffa00000 for CONFIG_SYS_NAND_BASE and adds other NAND supports in config file. It also moves environment(CONFIG_ENV_ADDR) outside of u-boot image, to make room for the increased code size with NAND enabled.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | This brings the core NAND code up to date with the Linux kernel. Since there were several drivers in Linux as of the last update that are not in u-boot, I'm not bringing over new drivers that have been added since in the absence of an interested party. I did not update OneNAND since it was recently synced by Kyungmin Park, and I'm not sure exactly what the common ancestor is. Signed-off-by: Scott Wood <scottwood@freescale.com>

* | bootm: Add subcommandsKumar Gala2008-10-29-2/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to break the steps of the bootm command into several subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go. This allows us to do things like manipulate device trees before they are passed to a booting kernel or setup memory for a secondary core in multicore situations. Not all OS types support all subcommands (currently only start, loados, ramdisk, fdt, and go are supported). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
