ARM: image: Add option for ignoring ep bit 3

2018-06-19T11:31:45Z

Add option to the booti_setup() which indicates to it that the caller requires the image to be relocated to the beginning of the RAM and that the information whether the image can be located anywhere in RAM at 2 MiB aligned boundary or not is to be ignored. This is useful ie. in case the Image is wrapped in another envelope, ie. fitImage and not relocating it but moving it would corrupt the envelope.

arm: Do not clear LR on exception in SPL

2018-06-18T18:43:13Z

When an exception or interrupt occurs the link register (LR) may contain the source of the exception, although we do not print the value it may still be extracted with a debugger. When in SPL we loop on getting and exception, but use a linking branch, which over-writes the LR value, use a regular branch instruction here. Signed-off-by: Andrew F. Davis

arm: print instructions pointed to by pc

2018-05-24T02:06:41Z

If an exception occurs in a loaded image and the relocation offset is unknown, it is helful to know the instructions pointed to by the program counter. This patch adds the missing output. A possible output is: Code: e1c560d0 e12fff1e e120077b e12fff1e (e7f7defb) The parentheses indicate the instruction causing the exception. The output can be disassembled using the decodecode script provided by the Linux kernel project. Signed-off-by: Heinrich Schuchardt

arm: v7R: Add support for enabling caches

2018-05-07T19:53:29Z

Cache maintenance procedure is same for v7A and v7R processors. So re-use cache-cp15.c file except for mmu parts. Tested-by: Michal Simek Signed-off-by: Lokesh Vutla Reviewed-by: Tom Rini

arm: v7: Kconfig: Introduce SYS_ARM_CACHE_CP15

2018-05-07T19:53:28Z

Certain ARM architectures like ARMv7-A, ARMv7-R has support for enabling caches using CP15 registers. To have a common support for all these architectures, introduce a Kconfig symbol SYS_ARM_CACHE_CP15 that selects cache-cp15.c Tested-by: Michal Simek Reviewed-by: Tom Rini Signed-off-by: Lokesh Vutla

arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A

2018-05-07T19:53:24Z

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

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

2018-05-07T14:24:31Z

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 multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam Signed-off-by: Tom Rini

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

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini
