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.
Notes:
- Board-dependend code for RPXLITE and RPXCLASSIC-based boards
placed to the drivers/rpx_pmcia.c file to avoid duplication.
Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
- drivers/i82365.c has been split into two parts located at
board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
the only boards using CONFIG_82365).
- Changes were tested for clean build and *very* *few* boards.
Update etags build target
* Improve NetConsole support: add support for broadcast destination
address and buffered input.
* Cleanup compiler warnings for GCC 3.3.x and later
* Fix problem in cmd_jffs2.c introduced by CFG_JFFS_SINGLE_PART patch
* Patch by Sascha Hauer, 28 Jun:
- add generic support for Motorola i.MX architecture
- add support for mx1ads, mx1fs2 and scb9328 boards
* Patches by Marc Leeman, 23 Jul 2004:
- Add define for the PCI/Memory Buffer Configuration Register
- corrected comments in cpu/mpc824x/cpu_init.c
* Add support for multiple serial interfaces
(for example to allow modem dial-in / dial-out)
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
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)
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
- Allow to call sysmon function interactively
- PIC on LWMON board needs delay after power-on
- Add missing RSR definitions for MPC8xx
- Improve log buffer handling: guarantee clean reset after power-on
- Add support for EXBITGEN board
- Add support for SL8245 board
- 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
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)
- Splashscreen support
- modem support
- sysmon support
- temperature dependend enabling of LCD
* Allow booting from old "PPCBoot" disk partitions
* Add support for TQM8255 Board / MPC8255 CPU
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)
