* MX5: factor out boot cause funciton to common codeJason Liu2011-04-27-0/+28

* ARM: mx31: Print the silicon versionFabio Estevam2011-04-27-2/+28
| | | | | | | | | | | Use the same method of the Linux kernel to print the MX31 silicon version on boot. Tested on a MX31PDK with a 2.0 silicon, where it shows: CPU: Freescale i.MX31 rev 2.0 at 531 MHz Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-27-4/+4
| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

* MX31: add support for MX31 watchdogStefano Babic2011-04-27-1/+37
| | | | | | | | | | | | | | | | | | The patch add CONFIG_HW_WATCHDOG to be used with the internal watchdog timer of the MX31 processor. Two function are exported for the board maintainers: mxc_hw_watchdog_enable mxc_hw_watchdog_reset The board maintainer can decide to use mxc_hw_watchdog_reset as hw_watchdog_reset, or to implement his own function to reset the watchdog. The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS (value in seconds). The MX31 allows values between 0.5 (CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

* arm: fix incorrect monitor protection region in FLASHPo-Yu Chuang2011-03-27-0/+86
| | | | | | | | | | | Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead.

| | | | | | | | | | | | | | | | | This change allows the davinci timer functions to be used before relocation since it avoids using static variables prior to BSS being made available. The code is based on that used in the at91 timers, modified to use a davinci specific hardware timer.

* | armv7: fix relocation skipAndreas Bießmann2010-12-09-2/+2
| | | | | | | | | | | | | | | | | | I doubt the stack_setup() was defective before: we load the current location of _start and compare against destination of relocate_code(). If we are already there we shoud skip the relocation and jump over to clear_bss. Before the clear_bss was also skipped. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* | arm: fixloop(): do not use r8 for relocationAndreas Bießmann2010-12-09-42/+42

* | arm: copy_loop(): use scratch registerAndreas Bießmann2010-12-09-70/+70
| | | | | | | | | | | | | | | | | | This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes.
