* nios: remove nios-32 archThomas Chou2010-05-28-3403/+0
| | | | | | The nios-32 arch is obsolete and broken. So it is removed. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>
* nios2: allow STANDALONE_LOAD_ADDR overridingThomas Chou2010-05-28-1/+1
| | | | | | | | | This patch allows users to override default STANDALONE_LOAD_ADDR. The gcclibdir path was duplicated in the standalone Makefile and can be removed. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* nios2: fix div64 issue for gcc4Thomas Chou2010-05-28-175/+856
| | | | | | | | | | | | | This patch fixes the run-time error on div64 when built with gcc4, which was reported by jhwu0625 on nios forum. It merges math support from libgcc of gcc4. This patch is copied from nios2-linux. It works with both gcc3 and gcc4. The old mult.c, divmod.c and math.h are removed.

* nios2: fix r15 issue for gcc4Thomas Chou2010-05-28-9/+2
| | | | | | | | | | The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* nios2: add gpio supportThomas Chou2010-05-28-0/+52
| | | | | | | | | | | | | This patch adds driver for a trivial gpio core, which is described in http://nioswiki.com/GPIO. It is used for gpio led and nand flash interface in u-boot. When CONFIG_SYS_GPIO_BASE is not defined, board may provide its own driver.

| * mpc83xx: don't shift pre-shifted ACR, SPCR, SCCR bitfield masks in cpu_init.cKim Phillips2010-05-21-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c7190f028fa950d4d36b6d0b4bb3fc72602ec54c "mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields" incorrectly shifted <register>_<bitfield> (e.g. ACR_PIPE_DEP) values that were preshifted by their definition in mpc83xx.h. this patch removes the unnecessary shifting for the newly utilized mask values in cpu_init.c, and prevents seemingly unrelated symptoms such as an mpc8379erdb board from locking up whilst performing a networking operation, e.g. a tftp.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 167cdad1372917bc11c636c359aad02625291fa9 "SERIAL: Enable port-mapped access" inadvertently broke 83xx nand boards by converting NS16550_init to use io accessors, which expanded the size of the generated code. this patch fixes the problem by removing icache functions from the nand builds, which somewhat follows commit 1a2e203b31d33fb720f2cf1033b241ad36ab405a "mpc83xx: turn on icache in core initialization to improve u-boot boot time" Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPD has minor change from Rev 1.2 to 1.3. This patch enables Rev 1.3. The difference has ben examined and the code is compatible. Speed bins is not verified on hardware for CL7 at this moment. This patch also enables SPD Rev 1.x where x is up to "F". According to SPD spec, the lower nibble is optionally used to determine which additinal bytes or attribute bits have been defined. Software can safely use defaults. However, the upper nibble should always be checked. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| * | 85xx/fsl-sata: Use is_serdes_configured() to determine if SATA is enabledKumar Gala2010-05-12-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the MPC85xx platform if we have SATA its connected on SERDES. Determing if SATA is enabled via sata_initialize should not be board specific and thus we move it out of the MPC8536DS board code. Additionally, now that we have is_serdes_configured() we can determine if the given SATA port is enabled and error out if its not in the driver. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new is_serdes_configured covers a broader range of devices than the PCI specific code. Use it instead as we convert away from the is_fsl_pci_cfg() code. Additionally move to setting LAWs for PCI based on if its configured. Also updated PCI FDT fixup code to remove PCI controllers from dtb if they are configured. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates bootcount_{store|load} for PowerPC by implementing a common version in arch/powerpc/lib/bootcount.c. This code is now used by all PowerPC variants that currently have these functions implemented. The functions now use the proper IO-accessor functions to read/write the values. This code also supports two different bootcount versions: a) Use 2 separate words (2 * 32bit) to store the bootcounter b) Use only 1 word (2 * 16bit) to store the bootcounter Version b) was already used by MPC5xxx.

Both of these locations are unsafe as those locations can be erased during a U-Boot update.

* | x86: Add RAM bootstrap functionalityGraeme Russ2010-05-06-6/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a parameter to the 32-bit entry to indicate if entry is from Real Mode or not. If entry is from Real Mode, execute the destructive 'sizer' routine to determine memory size as we are booting cold and running in Flash. If not entering from Real Mode, we are executing a U-Boot image from RAM and therefore the memory size is already known (and running 'sizer' will destroy the running image) There are now two 32-bit entry points. The first is the 'in RAM' entry point which exists at the start of the U-Boot binary image. As such, you can load u-boot.bin in RAM and jump directly to the load address without needing to calculate any offsets. The second entry point is used by the real-to-protected mode switch This patch also changes TEXT_BASE to 0x6000000 (in RAM). You can load the resulting image at 0x6000000 and simple go 0x6000000 from the u-boot prompt Hopefully a later patch will completely elliminate any dependency on TEXT_BASE like a relocatable linux kernel (perfect world) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

The unused memory region for ppc boot currently starts 1k below the do_bootm->bootm_start->arch_lmb_reserve stack ptr. This isn't enough since do_bootm->do_bootm_linux->boot_relocate_fdt calls printf which may very well use more than 1k stack space. Signed-off-by: Norbert van Bolhuis <nvbolhuis@aimvalley.nl>
