EHCI debug port finder
by Carl-Daniel Hailfinger 30 May '14

30 May '14

I wanted to know which physical port of my multiple USB controllers have the debug capability. There was no way to find that easily, so I created a tool which will do most of the work for the user. Example output: The following PCI devices support a USB debug port (says lspci): 0000:00:1d.7 The following PCI devices support a USB debug port (says the kernel): 0000:00:1d.7 PCI device 0000:00:1d.7, USB bus 3, USB physical port 1 Currently connected high-speed devices: /: Bus 03.Port 1: Dev 1, … [View More]

flashrom patch: add support for Abit AB-BM6 board
by Tim ter Laak 13 Sep '10

13 Sep '10

Hello all, This patch adds support for the Abit AB-BM6 mainboard to flashrom. The biggest part is a generic function to lower a GPIO line on the PIIX4E southbridge, copied and adapted from its ich_gpio_raise() counterpart (mostly lower instead of raise, followed names from the PIIX4E datasheet). The board specific function then uses this to lower GPO 26. Signed-off-by: Tim ter Laak <timl(a)scintilla.utwente.nl> --- The patch was made from the flashrom subdir, because svn diff from … [View More]the top-level coreboot dir (as per the directions in the Development Guidelines on the wiki) didn't seem to work for me. Probably because flashrom is fetched externally when checking out coreboot? Anyway, I hope this is okay. If you really prefer a diff from the top-level dir just let me know, and I'll regenerate it with gnu diff. Kind regards, Tim.
