* ARM: karo-tx6x: Fix DCD check operationsSascha Hauer2022-05-034-36/+35
| | | | | | | | | | | | | | | | | In f04deb4018 was discovered that we used the wrong names for the check operations. What we named "while_all_bits_clear" really was the operation "until_all_bits_clear" and likewise for the other operations, so this patch renamed the operations from "while_*" to "until_*". Additionally it was assumed that the users have the correct textual logic, but were compiled to the wrong result. At least for the Karo TX6X boards it was the other way round though: The texts were wrong, but the result was correct. This means, although they had the wrong text, the result was working on the hardware. Now f04deb4018 replaced "while_all_bits_clear" with "until_all_bits_set" and with this broke the DCD tables. Fix this by replacing them with the correct commands. Fixes: f04deb4018 ("i.MX/DCD compiler and interpreter: logic is different") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adapts all files that were identifed by licensecheck (https://salsa.debian.org/build-common-team/licensecheck.git) as licensed under the GPL. The copyright situation isn't trivially clear for these files, so I didn't replace the copyright statement here with machine-parseable tags. While touching these files also do some minor comment reformatting to get some uniform layout.

* | scripts: imx-image: rename dcdofs to ivtofsSascha Hauer2020-07-144-4/+4
|/ | | | | | | | | This renames the dcdofs config option in the imx-image tool to ivtofs. dcdofs is a misnomer. The DCD (Device Configuration Data) is only one part of the data linked into the IVT (Image Vector Table), but the meaning of the option is really the latter, not the former.

* ARM: Cleanup stack offset cargo cultSascha Hauer2019-09-091-4/+4
| | | | | | | | | Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16 bytes from the stack top. This is unnecessary as on ARM we have a stack that decrements before storing values. Substracting this offset probably goes back to the U-Boot version we forked from. Stop this now.

| * i.MX/DCD compiler and interpreter: logic is differentJuergen Borleis2018-03-264-37/+37
| | | | | | | | | | | | | | | | | | | | | | Reading the manual more carefully discovers a different logic for the DCD 'check' command. They use the term "until". In order to get the manual and the software in sync, this change switches to the term "until" as well. Changing must happen at compiler and interpreter level to make it work.

* | ARM: return positive offset in get_runtime_offset()Sascha Hauer2018-03-211-4/+4
|/ | | | | | | | | | | When we are linked at 0x0 and running at 0x01000000 then get_runtime_offset() should return 0x01000000 and not 0xff000000. This makes get_runtime_offset() more consistent and better understandable. This was tested on a Freescale i.MX53 Quickstart board. Additionally relocate_to_adr() was tested since that is normally not called. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: imx: use register defines in imxcfg files instead of plain numbersUwe Kleine-König2017-07-073-326/+335
| | | | | | | | | | | | | This makes the imxcfg files more readable and also makes it possible to share more assignments between machines that just differ by the used SoC. (Though I have to admit that in the cases converted here it just more easily allows to see that the RAM config differs more than probably necessary.) This change is intended to have no effect on the built artifacts. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

| | | | | | | | | | The device tree for the 801x variant only contains displays. The displays are not part of the SoM, but instead of the baseboard, so they should be described in a baseboard dts.
