2025-10-14tpm: Make U_BOOT_DRIVER entries uniqueTom Rini
All instances of the U_BOOT_DRIVER must use a unique name or they will lead to link time failures due to name space conflicts when both are present. In this case the driver was reusing the tpm_tis_i2c name.

2025-08-25tpm: tis_infineon: Cannot test unsigned for being negativeAndrew Goodbody
tpm_tis_i2c_get_burstcount returns a size_t but also returns -EBUSY if the TPM is surrently busy. As size_t is an unsigned type simply testing for < 0 will not work so change the test for being equal to -EBUSY which will work. Also remove the trivial comments. This issue was found by Smatch.

2025-08-25tpm: tpm_tis_infineon: Make use of 'z' for printing size_tTom Rini
When printing the contents of an size_t variable we need to use z prefix to the format character in order to get the correct format type depending on 32 or 64bit-ness.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master.

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-25tpm: disociate TPMv1.x specific and generic codeMiquel Raynal
There are no changes in this commit but a new organization of the code as follow. * cmd/ directory: > move existing code from cmd/tpm.c in cmd/tpm-common.c > move specific code in cmd/tpm-v1.c > create a specific header file with generic definitions for commands only called cmd/tpm-user-utils.h * lib/ directory: > move existing code from lib/tpm.c in lib/tpm-common.c > move specific code in lib/tpm-v1.c > create a specific header file with generic definitions for the library itself called lib/tpm-utils.h * include/ directory: > move existing code from include/tpm.h in include/tpm-common.h > move specific code in include/tpm-v1.h Code designated as 'common' is compiled if TPM are used. Code designated as 'specific' is compiled only if the right specification has been selected. All files include tpm-common.h. Files in cmd/ include tpm-user-utils.h. Files in lib/ include tpm-utils.h. Depending on the specification, files may include either (not both) tpm-v1.h or tpm-v2.h.

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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini

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>

Now, include/linux/errno.h is a wrapper of <asm-generic/errno.h>. Replace all include directives for <asm-generic/errno.h> with <linux/errno.h>. <asm-generic/...> is supposed to be included from <asm/...> when arch-headers fall back into generic implementation.
