* ppc: Move cpu/$CPU to arch/ppc/cpu/$CPUPeter Tyser2010-04-13-766/+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 Tjernlund2010-01-26-30/+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>

* [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
* * Patches by Denis Peter, 9 Sep 2003:wdenk2003-09-10-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | add FAT support for IDE, SCSI and USB * Patches by Gleb Natapov, 2 Sep 2003: - cleanup of POST code for unsupported architectures - MPC824x locks way0 of data cache for use as initial RAM; this patch unlocks it after relocation to RAM and invalidates the locked entries. * Patch by Gleb Natapov, 30 Aug 2003: new I2C driver for mpc107 bridge. Now works from flash. * Patch by Dave Ellis, 11 Aug 2003: - JFFS2: fix typo in common/cmd_jffs2.c - JFFS2: fix CFG_JFFS2_SORT_FRAGMENTS option - JFFS2: remove node version 0 warning - JFFS2: accept JFFS2 PADDING nodes - SXNI855T: add AM29LV800 support - SXNI855T: move environment from EEPROM to flash - SXNI855T: boot from JFFS2 in NOR or NAND flash * Patch by Bill Hargen, 11 Aug 2003: fixes for I2C on MPC8240 - fix i2c_write routine - fix iprobe command - eliminates use of global variables, plus dead code, cleanup.
* * Implement new mechanism to export U-Boot's functions to standalonewdenk2003-07-24-68/+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:wdenk2003-06-27-3/+0
| | | | | | | | | - 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)
* * Patches by Udi Finkelstein, 2 June 2003:wdenk2003-06-03-1/+1
| | | | | | | | | | | | | | | | | | | | | | - 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 lengthwdenk2003-05-30-8/+3
| | | | | | | | 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)
