2012-11-28x86: Put global data on the stackGraeme Russ
Putting global data on the stack simplifies the init process (and makes it slightly quicker). During the 'flash' stage of the init sequence, global data is in the CAR stack. After SDRAM is initialised, global data is copied from CAR to the SDRAM stack Signed-off-by: Graeme Russ <graeme.russ@gmail.com> Signed-off-by: Simon Glass <sjg@chromium.org>

2012-11-26spl/85xx: new SPL supportScott Wood
Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL and CONFIG_SPL_BUILD, respectively. CONFIG_NAND_SPL can be removed once the last mpc85xx nand_spl target is gone. CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't seem right to overload it for meaning SPL as well as nand_spl does. Even if it's somewhat appropriate for the main u-boot, the SPL itself isn't (necessarily) ramboot, and we don't have separate configs for SPL and main u-boot. It was also inconsistent, as other platforms such as mpc83xx didn't use CONFIG_RAMBOOT in this way. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>
2012-11-26spl/powerpc: introduce CONFIG_SPL_INIT_MINIMALScott Wood

2012-11-26spl/mpc85xx: move udelay to cpu codeScott Wood
It applies to non-Freescale 85xx boards as well as Freescale boards, so it doesn't belong in board/freescale. Plus, it needs to come out of nand_spl if it's to be used by the new SPL. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>
2012-11-26powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxxScott Wood
It's arch code and not a driver, so move it where it belongs. When it originally went into drivers/misc there was no 8xxx CPU directory. This will make new-SPL support a little easier since we can keep the CPU stuff together and not need to pull stuff in from drivers/misc. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>
2012-11-26powerpc/mpc85xx: fix TLB alignmentScott Wood
In the RAMBOOT/SPL case we were creating a TLB entry starting at CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly aligned for the TLB entry size. This turned out to not be the case with NAND SPL because the main U-Boot starts at an offset into the image in order to skip the SPL itself. Fix the TLB entry to always start at a proper alignment. We still assume that CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary thus requiring multiple TLB entries.

2012-11-26powerpc: change .fixup test to a GCC version testScott Wood
This was introduced by commit 244615197469dd6fe75ae082f38424b97c79aeaf, but it fails in a minimal SPL build where the only thing in arch/powerpc/lib is cache.c, which apparently doesn't generate any fixup records. The problem is reported to occur with GCC 3.x, so insist on GCC 4.0 or newer. Patterned after checkthumb as suggested by Tom Rini.

2012-11-26powerpc/mpc85xx: move debug tlb entry after TLB is in known stateScott Wood
Previously, in many if not all configs we were creating overlapping TLB entries which is illegal. This caused a crash during boot when moving p2020rdb NAND SPL into L2 SRAM.

2012-11-20musb-new: am35x backend driverIlya Yanok
Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>

2012-11-20usb: use linux/usb/ch9.h instead of usbdescriptors.hIlya Yanok
Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one. As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).

It is necessary to introduce a new system wide function- power_init_board() It turns out, that power initialization must be done as early as possible.
