[U-Boot] [PATCH] ppc4xx: Use common ns16550 functions in 4xx UART POST driver
by Stefan Roese 04 Oct '10

04 Oct '10

This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch.

[U-Boot] [PATCH v7 1/2] APM821xx: Add CPU support
by tmarri＠apm.com 04 Oct '10

04 Oct '10

From: Tirumala Marri <tmarri(a)apm.com> APM821XX is a new line of SoCs which are derivatives of PPC44X family of processors. This patch adds support of CPU, cache, tlb, 32k ocm, bootstraps, PLB and AHB bus. Signed-off-by: Tirumala R Marri <tmarri(a)apm.com> --- V6: * Correcting indentation.

[U-Boot] ppc44x - watchdog timers reboots during the image loading
by ame 04 Oct '10

04 Oct '10

On my 460ex board, i've tried to add CONFIG_WATCHDOG to the config and it appears to work until the board tries to boot. At that point I can count down about 10 seconds and the reboot happens. The 10s correlates with what I think the watchdog is being set to. I've inserted some WATCHDOG_RESET() invocations wrapping memmove_wd (which admittedly should not be needed), but it does not have an effect. The last message I see is ... Verifying Checksum ... OK ## Flattened Device Tree blob at ff3e0000 Booting using the fdt blob at 0xff3e0000 Uncompressing Kernel Image ... OK Loading Device Tree to 007fa000, end 007ffd2f ... OK Loading Ramdisk to 1ec58000, end 1efffc0c ... OK Then it instantly resets. If I remove CONFIG_WATCHDOG the board works and boots correctly. My u-boot is circa early 2009. From looking at the current u-boot it does not have the tcr and tsr registers "converted to uppercase", so I don't think it builds yet. I've verified the addresses of the spr and they look correct. Any thoughts or help are appreciated. I did notice the comments in cpu-init.c that my tcr is setup with 0xF0000000, I *think* this is actually 10s on a 800MHz board. Not sure where the 2.684 numbers originates as stated in the comments. I also changed the acknowledge of the watchdog to the following, though neither my changes nor the original have any effect. I've also verified that the code is getting included and built. Not sure what to try next. void reset_4xx_watchdog(void) { /* * Clear TSR(WIS) bit */ mtspr(tsr, 0xC0000000); } #endif /* CONFIG_WATCHDOG */

[U-Boot] Patches to support Ramtron SPI FRAMs
by Reinhard Meyer 04 Oct '10

04 Oct '10

Patch 1 adds generalisation to spi_flash.c to allow for table driven probing of JEDEC and NON-JEDEC conformant devices Patch 2 adds the actual Ramtron support Patch 2 requires Patch 1 to be applied first.
