If the bus is blocked because of a previously interrupted
transfer, up to eleven clocks are generated on the I2CSCL
line to complete the transfer and to free the bus.
With this fix pin I2CSCL (PG6) is really configured as GPIO
so the clock pulses are really generated.
Patch by Martin Krause, 04 Apr 2006
- Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
- creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
- moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
- moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
into cpu/arm920t/$(SOC)/
fix pll_pci_to_mem_multiplier table for MPC8245
* Patch by Anders Larsen, 22 Sep 2003:
enable timed autoboot on PXA
* Patch by David Müller, 22 Sep 2003:
- add $(CFLAGS) to "-print-libgcc-filename" so compiler driver
returns correct libgcc file path
- "latency" reduction of busy-loop waiting to improve "U-Boot" boot
time on s3c24x0 systems
* Patch by Jon Diekema, 19 Sep 2003:
- Add CFG_FAULT_ECHO_LINK_DOWN option to echo the inverted Ethernet
link state to the fault LED.
- In NetLoop, make the Fault LED reflect the link status. The link
status gets updated on entry, and on timeouts.
- 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)
- 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
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
boards, version 153 for Rev. 200 boards).
* Patch by Vladimir Gurevich, 12 Mar 2003:
Fix relocation problem of statically initialized string pointers
in common/cmd_pci.c
* Patch by Kai-Uwe Blöm, 12 Mar 2003:
Cleanup & bug fixes for JFFS2 code:
- the memory mangement was broken. It caused havoc on malloc by
writing beyond the block boundaries.
- the length calculation for files was wrong, sometimes resulting
in short file reads.
- data copying now optionally takes fragment version numbers into
account, to avoid copying from older data.
See doc/README.JFFS2 for details.
- minimal setup for CardBus bridges
- add EEPROM read/write support in the CS8900 driver
- add support for the builtin I2C controller in the Samsung s3c24x0 chips
- add support for MPL's VCMA9 (Samsung s3c2410 based) board
* Patch by Steven Scholz, 04 Feb 2003:
add support for RTC DS1307
* Patch by Reinhard Meyer, 5 Feb 2003:
fix PLPRCR/SCCR init sequence on 8xx to allow for
changes of EBDF by software
* Patch by Vladimir Gurevich, 07 Feb 2003:
"API-compatibility patch" for 4xx I2C driver
