* linux_compat: remove cpu_relax() defineMasahiro Yamada2015-07-22-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The macro cpu_relax() is defined by several headers in different ways. arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows: #define cpu_relax() barrier() On the other hand, include/linux/compat.h defines it as follows: #define cpu_relax() do {} while (0) If both headers are included from the same source file, the warning warning: "cpu_relax" redefined [enabled by default] is displayed. It effectively makes it impossible to include <linux/compat.h> from some sources. Drop the latter.

* kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada2014-09-16-1/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

* musb-new, dfu: first send request answer then call completionsHeiko Schocher2014-05-08-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | comment in ep0_txstate() states: "report completions as soon as the fifo's loaded; there's no win in waiting till this last packet gets acked". This is wrong for using dfu. In the dfu usecase we must send a PollTimeout to the host, so the host can wait until the U-Boot Code is ready for answering new usb requests. So the answer which contains the PollTimeout must send *before* U-Boot calls req->complete. The req->complete is used in the dfu case for flushing the medium, when entering DFU_STATE_dfuMANIFEST_SYNC state.

* musb-new: port of Linux musb driverIlya Yanok2012-11-20-0/+1089
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>
