* Blackfin: re-architect initcodeMike Frysinger2010-01-17-52/+169
| | | | | | | | The single initcode function was growing unwieldy, so split it up the distinct steps into their own function. This should making digesting the result much easier on people. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: move section length calculation to linker scriptMike Frysinger2010-01-17-16/+13
| | | | | | | The length of the sections is fixed at link time, so let the linker do the calculation rather than doing it ourselves at runtime. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | Add support to configure bus parking mode and master in bus arbitration configuration (ACR). Add this for the kmeter1 port: Configure bus arbiter with recommended values from Freescale to improve bus latency/throughput for application with intensive QuiccEngine activity.

| * mpc83xx: spd_sdram.c: Disable memory controller before initializingStefan Roese2010-01-07-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory controller could already be enabled, when spd_sdram() is called. This could be the case for example, when the SDRAM is initialized by the JTAG debugger. The "sync" after the register access via the accessor function is still needed, because the macro uses the sync before the real write is done. So until not all accesses are converted to using accessor functions, this sync still needs to be made "manually" here.

* | ppc/85xx: Make SPD DDR TLB setup code use dynamic entry allocationKumar Gala2010-01-05-6/+6
| | | | | | | | | | | | | | | | Now that we track which TLB CAM entries are used we can allocate entries on the fly. Change the SPD DDR TLB setup code to assume we use at most 8 TLBs (or the number free, which ever is fewer). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* USB Consolidate descriptor definitionsTom Rix2009-12-20-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The header files usb.h and usbdescriptors.h have the same nameed structure definitions for usb_config_descriptor usb_interface_descriptor usb_endpoint_descriptor usb_device_descriptor usb_string_descriptor These are out right duplicates in usb.h usb_device_descriptor usb_string_descriptor This one has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; These in usb.h have extra elements at the end of the usb 2.0 specified descriptor and are used. usb_config_descriptor usb_interface_descriptor The change is to consolidate the definition of the descriptors to usbdescriptors.h. The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'. As an example - if (iface->bInterfaceClass != USB_CLASS_HUB) + if (iface->desc.bInterfaceClass != USB_CLASS_HUB) This has been compile tested on MAKEALL arm, ppc and mips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>
