ARM memory layout fixes: the abort-stack is now set up in the
correct RAM area, and the BSS is zeroed out as it should be.
Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
of the linker scripts are replaced by '__bss_start' and '_end',
resp., which is a further step to eliminate unnecessary differences
between the implementation of the CPU architectures.
- Added Motorola CPU 8540/8560 support (cpu/85xx)
- Added Motorola MPC8540ADS board support (board/mpc8540ads)
- Added Motorola MPC8560ADS board support (board/mpc8560ads)
* Minor code cleanup
- fix spelling errors
- set GD_FLG_DEVINIT flag only after device function pointers
are valid
- Allow CFG_ALT_MEMTEST on systems where address zero isn't
writeable
- enable 3.rd UART (ST-UART) on PXA(XScale) CPUs
- trigger watchdog while waiting in serial driver
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)
- Hymod board database mods: add "who" field and new xilinx chip types
- provide new "init_cmd_timeout()" function so code external to
"common/main.c" can use the "reset_cmd_timeout()" function before
entering the main loop
- add DTT support for adm1021 (new file dtt/adm1021.c; config
slightly different. see include/configs/hymod.h for an example
(requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
CFG_DTT_ADM1021 defined)
- add new "eeprom_probe()" function which has similar args and
behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
config.mk to allow board configurations to override the GNU
linker script, selected via the LDSCRIPT, make variable, and to
give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
o correctly extends the timeout depending on the size of all
queued messages for both transmit and receive
o will not continue with receive if transmit times out
o ensures that the error callback is done for all queued tx
and rx messages
o correctly detects both tx and rx timeouts, only delivers one to
the callback, and does not overwrite an earlier error
o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
technically correct
- many Hymod board changes
* MPC823 LCD driver: Fill color map backwards, to allow for steady
display when Linux takes over
* Patch by Erwin Rol, 27 Feb 2003:
Add support for RTEMS (this time for real).
* Add support for "bmp info" and "bmp display" commands to load
bitmap images; this can be used (for example in a "preboot"
command) to display a splash screen very quickly after poweron.
* Add support for 133 MHz clock on INCA-IP board
- fix bug in BOOTP code (must use NetCopyIP)
- update of CSB226 port
- clear BSS segment on XScale
- added support for i2c_init_board() function
- update to the Innokom plattform
* Extend support for redundand environments for configurations where
environment size < sector size
Add code for AmigaOne board
(preliminary merge to U-Boot, still WIP)
* Patch by Jon Diekema, 12 Nov 2002:
- Adding URL for IEEE OUI lookup
- Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
being defined.
- In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
root-on-nfs macros are designed to switch how the default boot
method gets defined.
