Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
Old, obsolete and duplicated code was cleaned up and replace by the
new partitioning method. There are two possible approaches now:
* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.
- Add low-boot option for MPC8260ADS board (if lowboot is selected,
the jumper for the HRCW source should select flash. If lowboot is
not selected, the jumper for the HRCW source should select the
BCSR.
- change default load base address to 0x00400000
- add auto-complete support to the U-Boot CLI
- add support for NETTA and NETPHONE boards; fix NETVIA board
* Patch by Yuli Barcohen, 28 Mar 2004:
- Add support for MPC8272 family including MPC8247/8248/8271/8272
- Add support for MPC8272ADS evaluation board (another flavour of MPC8260ADS)
- Change configuration method for MPC8260ADS family
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
add Realtek 8019 ethernet driver
* Patch by Yuli Barcohen, 13 Nov 2003:
MPC826xADS/PQ2FADS cleanup
* Patch by Anders Larsen, 12 Nov 2003:
Update README to mark the PORTIO commands non-standard
According to the MPC8260 User's Manual, PCI_MODE signal should be
reflected in SCCR register, and local bus pins configuration is taken
from HRCW and appears in SIUMCR. For some reason it does not work
this way, so the only possibility to detect if the board is
configured in PCI mode is to check the BCSR. This patch sets SCCR and
SIUMCR according to the BCSR.
add delay to get I2C working with "imm" command and s3c24x0_i2c.c
* Patch by Richard Woodruff, 17 July 03:
- Fixed bug in OMAP1510 baud rate divisor settings.
* Patch by Nye Liu, 16 July 2003:
MPC860FADS fixes:
- add MPC86xADS support (uses MPC86xADS.h)
- add 866P/T core support (also MPC859T/MPC859DSL/MPC852T)
o PLPRCR changes
o BRG changes (EXTAL/XTAL restricted to 10MHz)
o don't trust gclk() software measurement by default, depend on
CONFIG_8xx_GCLK_FREQ
- add DRAM SIMM not installed detection
- use more "correct" SDRAM initialization sequence
- allow different SDRAM sizes (8xxADS has 8M)
- default DER is 0
- remove unused MAMR defines from FADS860T.h (all done in fads.c)
- rename MAMR/MBMR defines to be more consistent. Should eventually
be merged into MxMR to better reflect the PowerQUICC datasheet.
* Patch by Yuli Barcohen, 16 Jul 2003:
support new Motorola PQ2FADS-ZU evaluation board which replaced
MPC8260ADS and MPC8266ADS
- Correct flash and JFFS2 support for MPC8260ADS
- fix PVR values and clock generation for PowerQUICC II family
(8270/8275/8280)
* Patch by Bernhard Kuhn, 08 Jul 2003:
- add support for M68K targets
* Patch by Ken Chou, 3 Jul:
- Fix PCI config table for A3000
- Fix iobase for natsemi.c
(PCI_BASE_ADDRESS_0 is the IO base register for DP83815)
* Allow to enable "slow" POST routines by key press on power-on
* Fix temperature dependend switching of LCD backlight on LWMON
* Tweak output format for LWMON
- 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)
* Patch by Murray Jensen, 24 Jun 2003:
- make sure to use only U-boot provided header files
- fix problems with ".rodata.str1.4" section as used by GCC-3.x
- rewrite of the S3C24X0 register definitions stuff
- "driver" for the built-in S3C24X0 RTC
* Patches by Yuli Barcohen, 12 Jun 2003:
- Add MII support and Ethernet PHY initialization for MPC8260ADS board
- Fix incorrect SIUMCR initialisation caused by wrong Hard Reset
configuration word supplied by FPGA on some MPC8260ADS boards
* Patch by Pantelis Antoniou, 10 Jun 2003:
Unify status LED interface
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)
Add support for Motorola MPC8266ADS board
* Patch by Kyle Harris, 19 Feb 2003:
patches for the Intel lubbock board:
memsetup.S - general cleanup (based on Robert's csb226 code)
flash.c - overhaul, actually works now
lubbock.c - fix init funcs to return proper value
* Patch by Kenneth Johansson, 26 Feb 2003:
- Fixed off by one in RFTA calculation.
- No need to abort when LDF is lower than we can program it's only
minimum timing so clamp it to what we can do.
- Takes function pointer to function for reading the spd_nvram. Usefull
for faking data or hardcode a module without the nvram.
- fix other user for above change
- fix some comments.
* Patches by Brian Waite, 26 Feb 2003:
- fix port for evb64260 board
- fix PCI for evb64260 board
- fix PCI scan
* Patch by Reinhard Meyer, 1 Mar 2003:
Add support for EMK TOP860 Module
* Patch by Yuli Barcohen, 02 Mar 2003:
Add SPD EEPROM support for MPC8260ADS board
