* powerpc/mpc85xx: Add support for single source clockingPriyanka Jain2014-01-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Single-source clocking is new feature introduced in T1040. In this mode, a single differential clock is supplied to the DIFF_SYSCLK_P/N inputs to the processor, which in turn is used to supply clocks to the sysclock, ddrclock and usbclock. So, both ddrclock and syclock are driven by same differential sysclock in single-source clocking mode whereas in normal clocking mode, generally separate DDRCLK and SYSCLK pins provides reference clock for sysclock and ddrclock DDR_REFCLK_SEL rcw bit is used to determine DDR clock source -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in normal clocking mode by DDR_Reference clock -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in single source clocking mode by DIFF_SYSCLK Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is introduced. If "upgrade_available" is 0, "bootcount" is always 0 therefore no need to save the environment on u-boot boot, if "upgrade_available" is 1 "bootcount" is incremented in the environment and environment gets written on u-boot start. So the Userspace Applikation must set the "upgrade_available" and "bootcount" variable to 0 (for example with fw_setenv), if a boot was successfully. Signed-off-by: Heiko Schocher <hs@denx.de>

It also says other potential uses of DFU is beyond scope of the spec. Here such a beyond the scope use is being attempted - directly pumping binary images from host via USB to RAM. This facility is a developer centric one in that it gives advantage over upgrading non-volatile memory for testing new images every time during development and/or testing. Directly putting image onto RAM would speed up upgrade process. This and convenience was the initial thoughts that led to doing this, speed improvement over MMC was only 1 second though - 6 sec on RAM as opposed to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing DFU framework to avoid multiple copy for ram (if worth) may help, and on other platforms and other boot media like NAND maybe improvement would be higher. And for a platform that doesn't yet have proper DFU suppport for non-volatile media's, DFU to RAM can be used. Another minor advantage would be to increase life of mmc/nand as it would be less used during development/testing. usage: <image name> ram <start address> <size> eg. kernel ram 0x81000000 0x1000000 Downloading images to RAM using DFU is not something new, this is acheived in openmoko also. DFU on RAM can be used for extracting RAM contents to host using dfu upload. Perhaps this can be extended to io for squeezing out register dump through usb, if it is worth.

The TPL's size is sizeable, the maximum size is decided by the memory's size that TPL runs. It initializes the DDR through SPD code, and copys final uboot image to DDR.
