2012-11-26spl/nand: config symbol documentationScott Wood
Document parameters used for specifying the NAND image to be loaded. Also fix the definition of CONFIG_SPL_NAND_SIMPLE -- it's only nand_spl_simple.c, not the entire nand directory. The word "simple" is there for a reason. :-) Signed-off-by: Scott Wood <scottwood@freescale.com> --- v2: updated for makefile changes earlier in patchset
2012-11-26spl/nand: introduce CONFIG_SPL_NAND_DRIVERS, _BASE, and _ECC.Scott Wood
Some small SPLs do not use nand_base.c, and a subset of those also require a special driver. Some SPLs need software ECC but others can't fit it. All existing boards that specify CONFIG_SPL_NAND_SUPPORT have these symbols added to preserve existing behavior. Signed-off-by: Scott Wood <scottwood@freescale.com> -- v2: use positive logic for including bits of NAND, rather than a MINIMAL symbol that excludes things.
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.

2012-11-26serial/ns16550: wait for TEMT before initializingScott Wood
TEMT is set when the transmitter is totally empty and all output has finished. This prevents output problems (including a loss of synchronization observed on p2020 that persisted for quite a while) if SPL has output still on its way out. Signed-off-by: Scott Wood <scottwood@freescale.com> -- v2: fixed typo in subject, and explained what the bit does in the changelog
2012-11-26serial/ns16550: don't build serial_ns16550 with MIN_FUNCTIONSScott Wood
CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic ns16550 output code without pulling in things not needed by the SPL. This previously only worked with non-MULTI configs. Recently MULTI was made mandatory, and MIN_FUNCTIONS fails like this: drivers/serial/libserial.o: In function `calc_divisor.clone.0': serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq' drivers/serial/libserial.o: In function `_serial_getc': (.text._serial_getc+0x30): undefined reference to `NS16550_getc' drivers/serial/libserial.o: In function `_serial_tstc': (.text._serial_tstc+0x30): undefined reference to `NS16550_tstc' drivers/serial/libserial.o: In function `_serial_setbrg': (.text._serial_setbrg+0x3c): undefined reference to `NS16550_reinit' make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1 make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2 With MIN_FUNCTIONS we don't need anything from this file, so don't build it. The conditional needs to be in the file itself rather than the makefile, because the config symbols are only imported to the makefiles once, not separately for the SPL phase of the build.

2012-11-20musb-new: omap2plus backend driverIlya Yanok

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>

2012-11-20musb-new: port of Linux musb driverIlya Yanok
Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. 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).
