2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-02-21usb: gadget: sdp: fix pointer cast warnings for 64bit archsAndre Heider
The SDP protocol contains multiple 32bit pointers. Add a helper function to get a valid pointer from these values and use it. This fixes the following warnings: drivers/usb/gadget/f_sdp.c: In function ‘sdp_rx_data_complete’: drivers/usb/gadget/f_sdp.c:347:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] memcpy((void *)sdp->dnl_address, req->buf + 1, datalen); ^ drivers/usb/gadget/f_sdp.c: In function ‘sdp_jump_imxheader’: drivers/usb/gadget/f_sdp.c:625:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] entry = (void *)headerv2->entry; ^ drivers/usb/gadget/f_sdp.c: In function ‘sdp_handle_in_ep’: drivers/usb/gadget/f_sdp.c:668:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] memcpy(&data[1], (void *)sdp_func->dnl_address, datalen); ^ drivers/usb/gadget/f_sdp.c:679:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] status = sdp_jump_imxheader((void *)sdp_func->jmp_address); ^ Signed-off-by: Andre Heider <a.heider@gmail.com>

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>

Support U-Boot images in SPL so that u-boot.img files can be directly downloaded and executed. Furthermore support U-Boot scripts download and execution in full U-Boot so that custom recovery actions can be downloaded from the host in a third step.

2017-08-23usb: gadget: add SDP driverStefan Agner
Add SDP (Serial Downloader Protocol) implementation for U-Boot. The protocol is used in NXP SoC's boot ROM and allows to download program images. Beside that, it can also be used to read/write registers and download complete Device Configuration Data (DCD) sets. This basic implementation supports downloading images with the imx header format reading and writing registers.
