[U-Boot-Users] [PATCH] ppc4xx: Add pci_pre_init() for 405 boards
by Matthias Fuchs 24 Jun '07

24 Jun '07

ppc4xx: Add pci_pre_init() for 405 boards This patch adds support for calling a plattform dependant pci_pre_init() function for 405 boards. This can be used to move the current pci_405gp_fixup_irq() function into the board code. This feature can be enabled by defining CFG_PCI_PRE_INIT.

[U-Boot-Users] CFG_HZ value
by Umar Quershey 23 Jun '07

23 Jun '07

Hi- How should one define CFG_HZ? It seems that it's to be set to 1000. However my system clock speed is not this. What are the rules for setting this value? This constant is used in the timing functions of some boards. I am working on implementing the timing functions and have a hard time understanding how this could be the same across all boards. I have a timer on my board that I'd like to use to check for timeout conditions for an SPI Controller driver. I have adapted the timing functions in cpu/arm926ejs/omap/timer.c, but there also CFG_HZ is used. Should I replace the CFG_HZ with my real system clock speed? BTW, I have to read a register at boot time to determine what speed I am running at. I do this early on and save a variable 'clock_speed' that other functions can use to determine the system clock speed. Regards, Umar

[U-Boot-Users] How to add device tree support to a board?
by Gerhard Pircher 22 Jun '07

22 Jun '07

Hi, I'm trying to understand how to add flatten device tree support to a specific board (MAI/AmigaOneG3SE in this case). Besides setting CONFIG_OF_LIBFDT, is it necessary to add any code to the board's platform code? Which nodes are automatically added to the fdt by U-boot? Does the device tree include nodes for e.g. the PCI bus and its devices? regards, Gerhard PS: Please put me on CC: -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

Can somebody tell me what the above code snippet is good for? I cannot see how to run the transfer over a line not being the console but maybe I have missed something. Wolfgang.
