The new common spi framework and spi flash subsystem provides all the same functionality as the old Blackfin-specific driver, so punt the old one as it has been sticking around long enough. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The default storage location for bootcount is EVT0. This version uses one 32bit value and combines the magic/count value in the upper/lower 16bits. If there is demand for more, should be easy to do. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Avoid banging on the trace MMRs when debugging is disabled, avoid calling the funcs multiple times in a row, disable the trace buffer earlier in the exception handler to avoid eating more user entries, and dump the buffer before calling the kgdb hook. This way we maximize useful debugging info up front rather than needing external tools (like gdb/serial/etc...). Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

Change the return type of the *printf() functions to the standard "int"; no changes are needed but returning the already available length count. This will save a few additional strlen() calls later... Signed-off-by: NWolfgang Denk <wd@denx.de>

Remove some INFERNO related #ifdef's from common environment code by fixing the board configuration settings (add CONFIG_ENV_SECT_SIZE). While we are at it, fix comment which incorrectly talks about 4 KB environment size, while it's actually 0x4000 = 16 KiB. Signed-off-by: NWolfgang Denk <wd@denx.de> Cc: Rolf Offermanns <rof@sysgo.de>

This patch adds support for the T3CORP board, based on the AppliedMicro (APM) PPC460GT. Signed-off-by: NStefan Roese <sr@denx.de>

Background Info: Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via init.S) to speed up the boot process. In relocate_code (start.S) the cache inhibit attribute for this TLB is set to disable cache. This is needed for the CFI FLASH driver. This patch now cleans this code up: - CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not defined in the top of this file. This way, we can remove an ugly #ifdef in this code. - Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..." statement with "#if defined(CONFIG_440)". - Remove unnecessary cache invalidate calls resulting in faster bootup.

As described in item #10 of the SDRAM initialization (chapter 22.2.9 of the PPC460EX/EXr/GT users manual), RDSS may need to be adjusted. The code for this is now factored out and executed for non-SPD based boards as well. Signed-off-by: NStefan Roese <sr@denx.de>

This patch makes it possible to overwrite the default auto-calibration scan window (SDRAM_WRDTR.[WDTR], SDRAM_CLKTR.[CKTR] values) with board specific values. The parameters of the weak default function are corrected as well. This way we don't need the casts any more. This feature will be used by an upcoming PPC460GT board port.

By not defining CONFIG_SYS_PCI_MASTER_INIT and CONFIG_SYS_PCI_TARGET_INIT, PCI support (host and adapter) will not be enabled. But it's still possible to use the U-Boot PCI infrastructure for the PCIe ports. This configuration option is needed for a new 460GT board, which uses PCIe but has PCI disabled.

This patch enables booting with option E on the PPC460EX/EXr/GT. When booting with Option E, the PLL is in bypass, CPR0_PLLC[ENG]=0. The Software Boot Configuration Procedure is needed to engage the PLL and perform a chip reset. Signed-off-by: NStefan Roese <sr@denx.de>

At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: NMike Frysinger <vapier@gentoo.org>

This patch adds redundant environment for environment in SPI flash. I took env_flash.c as an example and slightly modified it. Apart from adapting things to SF, I also slightly changed the decision logic to use area 2 as a default in case the flags are wrong because not having a default path worried me. I did not add a section for CONFIG_ENV_IS_IN_SPI_FLASH in environment.h because I did not understand if this is desired and/or needed. So to use the feature, one has to set CONFIG_ENV_OFFSET_REDUND _and_ CONFIG_SYS_REDUNDAND_ENVIRONMENT. I checked it by powering off my board several times during flash erase or write, because I do not know if there are other stress test scenarios.

This avoids a build warning that you see if anyone in the header chain has included io.h (which is coming shortly). The previous code redefined readl/writel; this patch renames it to be specific to ohci. The defines are also moved from ohci-hcd.c to ohci.h. Signed-off-by: NBecky Bruce <beckyb@kernel.crashing.org>

MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support 500mA of power.We need to program MUSB PHY to use external Vbus for this purpose. Adding 'extvbus' member in musb_config structure which should be set by all the boards where MUSB interface is using external Vbus supply. Also added ULPI bus control register read/write abstraction for Blackfin processor as it doesn't have ULPI registers.

Changed musb_config initialization for omap3.c, davinci.c and da8xx.c using name of structure fields.
