[U-Boot] [PATCH] net: phy: micrel: add support for KSZ8895 switch in SMI mode
by Philippe De Muyter 30 Jan '15

30 Jan '15

This patch adds a phy driver for the Micrel KSZ8895 switch. As the SoC MAC is directly connected to the switch MAC the link to the switch is always up. But the KSZ8895 switch can be hardwired in three configuration modes : - not configurable with eventually an eeprom-stored configuration - configurable by the mdio/mdc connection (SMI protocol) - configurable by a SPI connection. In not configurable mode, the switch starts automatically, but in the other modes, it must be started programmatically, by writing 1 in configuration register 1. We only support the not configurable and mdio/mdc (aka SMI) modes here.

[U-Boot] [PATCH 0/3] Serial Flash: call spi_flash_free more coherently
by Valentin Longchamp 15 Oct '14

15 Oct '14

Some board require spi_flash_free to be called after all the accesses, in order, for instance, to restore the pin multiplexing configuration in the case where the SPI pins are multiplexed. This patch series tries to enhance this. Patch 1 adds spi_flash_free calls to env_sf so that the SPI interface is always "cleaned up" after the env read/writes. Patch 2 adds a 'sf release' command that implicitly calls spi_flash_free and is thus the pendant of 'sf probe'. Patch 3 uses the 'sf command' for the km_arm board scripts.

[U-Boot] Call for participation in the U-Boot Mini Summit 2014
by Detlev Zundel 02 Oct '14

02 Oct '14

Hi, as already indicated, we are looking forward to our next U-Boot Mini Summit at Embedded Linux Conference Europe 2014 which will take place in Düsseldorf, Germany from October 13 - 15. The call for papers of the main conference is now open[1] and if you want to submit a talk for the main tracks, you should note the deadline of July 11. For our U-Boot Mini Summit, I'd like to get the schedule completed synchronized to the schedule release of the main event, which is August 12. So please submit talk proposals here with at least me on CC. To coordinate the event better, I have setup another wiki page[2] that can and _should_ be edited by the interested parties. Feel free for example to add yourself to the "interested participants" so that we get an idea of how many of the U-Boot developers will be there.
