common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

videomodes: Relax EDID validation checks for hsync/vsync pulse width

2019-01-28T20:20:05+00:00

Current EDID detailed timing parser errors out when either horizontal or vertical pulse sync width is 0, thus not allowing a display with EDID listed below work properly. EDID below works ok within Linux although it warns about these two fields being 0. Therefore relax the checks a bit so we can actually use this the screen out of the box. Of-course, this display itself is somewhat quirky display with following anti-features: - HPD pin is not usable - although resolution is 640x480, only top 240 pixels are visible $ xxd -p display.edid 00ffffffffffff0005a1e00301000000150f0103800f05780a0f6ea05748 9a2610474f200000010101010101010101010101010101012a08804520e0 0b1020004000953600000018000000fd0034441a2403000a202020202020 0000001000310a20202020202020202020200000001000002a4030701300 782d1100001e006b $ edid-decode display.edid EDID version: 1.3 Manufacturer: AMA Model 3e0 Serial Number 1 Digital display Maximum image size: 15 cm x 5 cm Gamma: 2.20 RGB color display First detailed timing is preferred timing Display x,y Chromaticity: Red: 0.6250, 0.3398 Green: 0.2841, 0.6044 Blue: 0.1494, 0.0644 White: 0.2802, 0.3105 Established timings supported: 640x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 25.175 MHz Standard timings supported: Detailed mode: Clock 20.900 MHz, 149 mm x 54 mm 640 672 672 709 hborder 0 480 484 484 491 vborder 0 -hsync -vsync VertFreq: 60 Hz, HorFreq: 29478 Hz Monitor ranges (GTF): 52-68Hz V, 26-36kHz H, max dotclock 30MHz Dummy block Dummy block Checksum: 0x6b (valid) Signed-off-by: Priit Laes Signed-off-by: Priit Laes

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also. Suggested-by: Wolfgang Denk Signed-off-by: Simon Glass
