2010-04-13ppc: Move cpu/$CPU to arch/ppc/cpu/$CPUPeter Tyser
Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-01-26ppc: Use r12 instead of r14 as GOT pointer.Joakim Tjernlund
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>
2010-01-26ppc: Loose GOT access in IRQJoakim Tjernlund
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>
2009-10-08relocation: Do not relocate NULL pointers.Joakim Tjernlund
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>
2009-03-188xx, icache: enabling ICache not before running from RAMHeiko Schocher
with the new CONFIG_SYS_DELAYED_ICACHE config option, ICache is not enabled before code runs from RAM. Signed-off-by: Heiko Schocher <hs@denx.de>
2008-12-06Update U-Boot's build timestamp on every compilePeter Tyser
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>

2007-06-22[ppc] Fix build breakage for all non-4xx PowerPC variants.Rafal Jaworowski
- adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros - minor 4xx cleanup
2004-04-08* Patch by Mark Jonas: Remove config.tmp files only whenwdenk
unconfiguring the board * Adapt RMU board for bigger flash memory * Test fix for ethernet problems on MPC5200
2003-08-28* Fix ICU862 environment problemwdenk
* Fix RAM size detection for RMU board * Implement "reset" for MGT5100/MPC5200 systems
2003-07-27* Patch by Scott McNutt, 21 Jul 2003:wdenk
Add support for LynuxWorks Kernel Downloadable Images (KDIs). Both LynxOS and BlueCat linux KDIs are supported. * Patch by Richard Woodruff, 25 Jul 2003: use more reliable reset for OMAP/925T * Patch by Nye Liu, 25 Jul 2003: fix typo in mpc8xx.h * Patch by Richard Woodruff, 24 Jul 2003: Fixes for cmd_nand.c: - Fixed null dereferece which could result in incorrect ECC values. - Added support for devices with no Ready/Busy signal hooked up. - Added OMAP1510 read/write protect handling. - Fixed nand.h's ECCPOS. A conflict existed with POS5 and badblock for non-JFFS2. - Switched default ECC to be JFFS2.
2003-07-24* Implement new mechanism to export U-Boot's functions to standalonewdenk
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)
2003-06-27* Code cleanup:LABEL_2003_06_27_2340wdenk
- 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)
2003-06-03* Patches by Udi Finkelstein, 2 June 2003:LABEL_2003_06_04_0200wdenk
- 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
2003-05-30* Get (mostly) rid of CFG_MONITOR_LEN definition; compute real lengthLABEL_2003_05_30_1450wdenk
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)
2003-05-22* Patch by Dave Ellis, 22 May 2003:LABEL_2003_05_23_0055wdenk
Fix problem with only partially cleared .bss segment * Patch by Rune Torgersen, 12 May 2003: get PCI to work on a MPC8266ADS board; incorporate change to cpu/mpc8260/pci.c to enable overrides of PCI memory parameters
2003-01-11* Restrict baudrate settings on LWMON to higher speedsLABEL_2003_01_11_1050wdenk
when watchdog is on * Update baudrate in bd_info when it gets changed * Add watchdog trigger points while waiting for serial port (so far only 8xx -- needed on LWMON with 100ms watchdog) * Improve command line tool to access the U-Boot's environment (figuration of the utility, using a config file)
2002-12-07* Patch by Hans-Joerg Frieden, 06 Dec 2002LABEL_2002_12_07_0120wdenk
Fix misc problems with AmigaOne support * Patch by Chris Hallinan, 3 Dec 2002: minor cleanup to the MPC8245 EPIC driver * Patch by Pierre Aubert , 28 Nov 2002 Add support for external (SIU) interrupts on MPC8xx * Patch by Pierre Aubert , 28 Nov 2002 Fix nested syscalls bug in standalone applications * Patch by David Müller, 27 Nov 2002: fix output of "pciinfo" command for CardBus bridge devices. * Fix bug in TQM8260 board detection - boards got stuck when board ID was not readable
