* FPU POST: fix warnings when building with 2.18 binutilsYuri Tikhonov2009-01-24-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compile u-boot with the 2.18 binutils the following warning messages for each object file in post/lib_ppc/fpu/ is produced at the linking stage: post/libpost.a(acc1.o) uses hard float, u-boot uses soft-float ... This is because of the fact that, in general, the soft-float and hard-float ABIs are incompatible; the 2.18 binutils do checking of the Tag_GNU_Power_ABI_FP attribute of the files to be linked, and produce the worning like above if these are not compatible. The incompatibility of ABIs is concerned only the float values: e.g. the soft-float ABI assumes the float argument passing in the pair of rX registers, and the hard-float ABI assumes passing of the float argument in the fX register. When we don't pass the float arguments between the functions compiled with different floatness, then such an application will work correctly. This is the case for the FPU POST: u-boot (compiled with soft-float) doesn't pass to (and doesn't get from) the FPU POST functions any floats; there are no functions exported from the post/lib_ppc/fpu/ objects which would work with float parameters/returns too. So, we can reassure the linker not to worry about the difference in ABI attributes of linking files just by setting the 'soft-float' attribute for the objects in post/lib_ppc/fpu. And this patch does this. Also, to avoid passing both soft- and hard-float options in CFLAGS when compiling the files from post/lib_ppc/fpu (which is OK, but looks rather dirty) this patch removes the soft-float string from CFLAGS in post/lib_ppc/fpu/Makefile.

* Add support for Maxim's DS4510 I2C devicePeter Tyser2009-01-24-0/+504
| | | | | | | | | | | | | Initial support for the DS4510, a CPU supervisor with integrated EEPROM, SRAM, and 4 programmable non-volatile GPIO pins. The CONFIG_DS4510 define enables support for the device while the CONFIG_CMD_DS4510 define enables the ds4510 command. The additional CONFIG_DS4510_INFO, CONFIG_DS4510_MEM, and CONFIG_DS4510_RST defines add additional sub-commands to the ds4510 command when defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

| | | | | | | | | | | Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the !CONFIG_AUTOBOOT_KEYED case.

* Added MMCR reset functionalityGraeme Russ2009-01-24-0/+10
| | | | | | | | | | | | | | | | Reset function specific to AMD SC520 microcontroller - Is more of a 'hard reset' that the triple fault. Requires CONFIG_SYS_RESET_SC520 to be defined in config I would have liked to add this to a new file (cpu/i386/sc520/reset.c) but ld requires that a object file in a library arhive MUST contain at least one function which does not override a weak function (and is called from outside the object file) in order for that object file to be extracted from the archive. This would be the only function on the new file, and hence, will never get linked in. Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
* Moved generic (triple fault) reset codeGraeme Russ2009-01-24-16/+17
| | | | | | | | | | | | Moved from interrupts.c to cpu.c and made into a weak function to allow vendor specific override Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be added to the vendor specific code without the need to remember to #undef usage of the generic method and if you forget to include your custom reset method, you will always get the default.

| | | | | | | | | | | | | | | | | | | | | | | | Error with CONFIG_NAND_LEGACY in common/cmd_nand.c: With current code "nand read.jffs2s" (read and skip bad blocks) is always interpreted as "nand read.jffs2" (read and fill bad blocks with 0xff).

| * NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger2009-01-23-77/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and changes the default from 8 to 1 for the legacy and the new MTD NAND layer. This allows to remove all NAND_MAX_CHIPS definitions in the board config files because none of the boards use multi chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440 define #define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE but that's bogus and did not work anyhow.

| * NAND: Fix cache and memory inconsistency issueDave Liu2009-01-23-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We load the secondary stage u-boot image from NAND to system memory by nand_load, but we did not flush d-cache to memory, nor invalidate i-cache before we jump to RAM. When the system has cache enabled and the TLB/page attribute of system memory is cacheable, it will cause issues. - 83xx family is using the d-cache lock, so all of d-cache access is cache-inhibited. so you can't see the issue. - 85xx family is using d-cache, i-cache enable, partial cache lock. you will see the issue. This patch fixes the cache issue. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in fdt_resize() to extend the fdt size to end on a page boundary is wrong for fdt's not located at an address aligned on a page boundary. What's even worse, the code would make actualsize shrink rather than grow if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(), causing fdt_add_mem_rsv to fail. Fix it by aligning end address (blob + size) to a page boundary instead. For aligned fdt's this is equivalent to what we had before. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
