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.
The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
integrated in a little aluminium case.
Patch by Martin Krause, 8 Jun 2006
Some code cleanup
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.
- Add support for mpc8xx USB device.
- Add support for Common Device Class - Abstract Control Model USB console.
- Add support for flow control in USB slave devices.
- Add support for switching between gserial and cdc_acm using environment.
- Minor changes to usbdcore_omap1510.c usbdcore_omap1510.h
- Update usbcore slightly to ease host enumeration.
- Fix non-portable endian problems in usbdcore and usbdcore_ep0.
- Add AdderUSB_config as a defconfig to enable usage of the USB console
by default with the Adder87x U-Boot port.
