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>

2017-05-15omap3: Drop CONFIG_OMAP3_EVM, switch to CONFIG_TARGET_OMAP3_EVM when neededTom Rini
We make use of CONFIG_OMAP3_EVM today to know when to do a specific tweak in MUSB. This can be tested on via CONFIG_TARGET_OMAP3_EVM instead, so switch there so we can drop the now unused symbol CONFIG_OMAP3_EVM. In investigating what to do about the symbol usage we see that the cairo board defines the same function, but never called it (as it does not define CONFIG_OMAP3_EVM) and was just returning anyhow, so drop that function from that board.

2014-11-20include: move various macros to include/linux/kernel.hMasahiro Yamada
U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

2014-03-10usb: create common header virtual root hub descriptorsStephen Warren
Many USB host controller drivers contain almost identical copies of the same virtual root hub descriptors. Put these into a common file to avoid duplication. Note that there were some very minor differences between the descriptors in the various files, such as: - USB 1.0 vs. USB 1.1 - Manufacturer/Device ID - Max packet size - String content I assume these aren't relevant.

2013-10-10usb: Prevent using reserved registers on DM36x usbAndrew Murray
The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this bit is reserved on the DM36x. Thus this patch ensures that the reserved bit is not accesssed. It has been observed that some USB devices will fail to enumerate with errors such as 'error in inquiry' without this patch. See http://www.ti.com/litv/pdf/sprufh9a for details.

These functions are used in the file using calls such as if (!wait_until... Where a -1 is returned it is mishandled and treated as success instead of a CRC error. This patch addresses this.

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).

The USB spec says that 32 bytes is the minimum required alignment. However on some platforms we have a larger minimum requirement for cache coherency. In those cases, use that value rather than the USB spec minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here as we are not allowed to have tests inside of align(...).

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
