* ppc: Move cpu/$CPU to arch/ppc/cpu/$CPUPeter Tyser2010-04-13-874/+0

* ppc: Use r12 instead of r14 as GOT pointer.Joakim Tjernlund2010-01-26-5/+6
| | | | | | | | r14 is not supposed to be clobbered by functions. Switch to r12 and call GET_GOT when needed. This will allow u-boot to loose the -ffixed-r14 gcc option. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* ppc: Loose GOT access in IRQJoakim Tjernlund2010-01-26-33/+3
| | | | | | | | Using the GOT in IRQ handlers requires r14 to be -ffixed-r14. Avoid this by relocatate transfer_to_handler too. This will allow to free up r14 later on. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-2/+4
| | | | | | | | | | NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* Update U-Boot's build timestamp on every compilePeter Tyser2008-12-06-1/+2
| | | | | | | Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* 74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cacheDave Liu2008-10-31-4/+4
| | | | | | | | | | | | | | | | | | The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7 mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache This is needed in unlock_ram_in_cache() because it is called from C and will corrupt the small data area anchor that is kept in R2. lock_ram_in_cache() is modified similarly as good coding practice, but is not called from C. Signed-off-by: Nick Spence <nick.spence@freescale.com> also, the r2 is used as global data pointer. Signed-off-by: Dave Liu <daveliu@freescale.com>

* PPC: Create and use CONFIG_HIGH_BATSBecky Bruce2008-06-03-3/+3
| | | | | | | | | | | Change all code that conditionally operates on high bat registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS instead of the myriad ways this is done now. Define the option for every config for which high bats are supported (and enabled by early boot, on parts where they're not always enabled) Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* [ppc] Fix build breakage for all non-4xx PowerPC variants.Rafal Jaworowski2007-06-22-2/+2
| | | | | - adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros - minor 4xx cleanup
* [PATCH] Add support for Prodrive P3M750 & P3M7448 (P3Mx) boardsStefan Roese2006-11-29-3/+5
| | | | | | | | | This patch adds support for the Prodrive P3M750 (PPC750 & MV64460) and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are quite similar and share the same board directory "prodrive/p3mx" and the same config file "p3mx.h". Signed-off-by: Stefan Roese <sr@denx.de>

* * The PS/2 mux on the BMS2003 board needs 450 ms after power onwdenk2004-01-20-1/+1
| | | | | | | | | | | | before we can access it; add delay in case we are faster (with no CF card inserted) * Cleanup of some init functions * Make sure SCC Ethernet is always stopped by the time we boot Linux to avoid Linux crashes by early packets coming in. * Accelerate flash accesses on LWMON board by using buffered writes
* * Patch by Ronen Shitrit, 10 Dec 2003:wdenk2004-01-03-1/+6
| | | | | | | Add support for the Marvell DB64360 / DB64460 development boards * Patch by Detlev Zundel, 10 Dec 2003: fix dependency problem in examples/Makefile
* * Implement new mechanism to export U-Boot's functions to standalonewdenk2003-07-24-69/+1
| | | | | | | | applications: instead of using (PPC-specific) system calls we now use a jump table; please see doc/README.standalone for details * Patch by Dave Westwood, 24 Jul 2003: added support for Unity OS (a proprietary OS)
* * Code cleanup:wdenk2003-06-27-82/+82
| | | | | | | | | - remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)

| | | | | | | | | | | | | | | | | | | | | | - Added support for custom keyboards, initialized by defining a board-specific drv_keyboard_init as well as defining CONFIG_KEYBOARD . - Added support for the RBC823 board. - cpu/mpc8xx/lcd.c now automatically calculates the Horizontal Pixel Count field. * Fix alignment problem in BOOTP (dhcp_leasetime option) [pointed out by Nicolas Lacressonnière, 2 Jun 2003] * Patch by Mark Rakes, 14 May 2003: add support for Intel e1000 gig cards. * Patch by Nye Liu, 3 Jun 2003: fix critical typo in MAMR definition (include/mpc8xx.h) * Fix requirement to align U-Boot image on 16 kB boundaries on PPC. * Patch by Klaus Heydeck, 2 Jun 2003 Minor changes for KUP4K configuration
* * Get (mostly) rid of CFG_MONITOR_LEN definition; compute real lengthwdenk2003-05-30-10/+5
| | | | | | | | instead CFG_MONITOR_LEN is now only used to determine _at_compile_ _time_ (!) if the environment is embedded within the U-Boot image, or in a separate flash sector. * Cleanup CFG_DER #defines in config files (wd maintained only)
