* ppc: Allow boards to specify how much memory they can mapKumar Gala2008-03-25-0/+11
| | | | | | | | For historical reasons we limited the stack to 256M because some boards could only map that much via BATS. However newer boards are capable of mapping more memory (for example 85xx is capble of doing up to 2G). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* The patch introduces the alternative configuration of the log buffer for the ↵Yuri Tikhonov2008-03-18-0/+4
| | | | | | | | | | | | | | lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5). To enable this, alternative, configuration the U-Boot board configuration file for lwmon5 includes the definitions of alternative addresses for header (CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR). The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set, and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).

* lwmon5: enable hardware watchdogYuri Tikhonov2008-02-22-3/+11
| | | | | | | | | | | | | Some boards (e.g. lwmon5) may use rather small watchdog intervals, so causing it to reboot the board if U-Boot does a long busy-wait with udelay(). Thus, for these boards we have to restart WD more frequently. This patch splits the busy-wait udelay() into smaller, predefined, intervals, so that the watchdog timer may be resetted with the configurable (CONFIG_WD_PERIOD) interval.

* API for external applications.Rafal Jaworowski2008-01-09-0/+5
| | | | | | | | | | | | | | This is an API for external (standalone) applications running on top of U-Boot, and is meant to be more extensible and robust than the existing jumptable mechanism. It is similar to UNIX syscall approach. See api/README for more details. Included is the demo application using this new framework (api_examples). Please note this is still an experimental feature, and is turned off by default. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During config transactions on the PCIe bus an attempt to scan for a non-existent device can lead to a machine check exception with certain peripheral devices.

CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically (such as by switch on board), this flag should be set. CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot relocates to RAM, this flag should be set. CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the system hang in exception, this flag should be set. There is a design issue for tsi108/109 pci configure read. When pci scan the slots, if there is no pci card, the tsi108/9 will cause a machine check exception for mpc7448 processor.
