- change gpio pin settings: - gpio pin 6[13] (PLC reset) default value low - gpio pin 6[0] (TPM reset) default value low - 4 new GPIO pins pin i/o name - 3[9] input Board Type - 2[7] input HW-ID0 - 2[6] input HW-ID1 - 2[3] input HW-ID2 - read board type and hw id from gpio pins on the enbw_cmc board, and use board type for setting up different gpio pin settings. - do not pass "davinci_mmc.use_dma=0" to linux, as MMC now works with DMA. - update logbuf support: store post word in RTC scratch register - add support for configuring KSZ8864RMN switch through a config file on u-boot startup.

On the enbw_cmc board is a KSZ8864RMN switch which needs
|
|
configured through spi before working. This is done on
|
|
startup from u-boot through a config file stored at an
|
|
address specified in the "hwconfig" environment variable,
|
|
subcommand "config".
|
|
|
|
For example on the enbw_cmc board:
|
|
|
|
hwconfig=switch:lan=on,pwl=off,config=0x60160000
|
|
|
|
The file has the following structure:
|
|
|
|
- a comment starts with a '#' or a ';' and ends with a newline
|
|
- The switch needs for its config a reg/value pair, so we
|
|
have two columns in the file:
|
|
reg : contains the register address
|
|
value: contains a 8 bit register value
|
|
This 2 columns are seperated through space or tab.
|
|
|
|
example (minimal configuration on the enbw_cmc board):
|
|
|
|
;reg value comment
|
|
