Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

2025-09-02memtest: remove use of vu_long typedef in mem_test_altRasmus Villemoes
Hiding a qualifier such as "volatile" inside a typedef makes the code much harder to understand. Since addr and dummy being volatile-qualified are important for the correctness of the test code, make it more obvious by spelling it out as "volatile ulong".

2025-09-02memtest: only call schedule() once for every 256 wordsRasmus Villemoes
A function call itself for every word written or read+written in these loops is bad enough. But since the memory test must be run with dcache disabled, the schedule() call, traversing the linked list of registered cyclic clients, and accessing the 'struct cyclic_info' for each to see if any are due for a callback, is quite expensive. On a beagleboneblack, testing a modest 16MiB region takes 2.5 minutes: => dcache off => time mtest 0x81000000 0x82000000 0 1 Testing 81000000 ... 82000000: Iteration: 1 Tested 1 iteration(s) with 0 errors. time: 2 minutes, 28.946 seconds There is really no need for calling schedule() so frequently. It is quite easy to limit the calls to once for every 256 words by using a u8 variable. With that, the same test as above becomes 37 times faster: => dcache off => time mtest 0x81000000 0x82000000 0 1 Testing 81000000 ... 82000000: Iteration: 1 Tested 1 iteration(s) with 0 errors. time: 4.052 seconds Note that we are still making a total of 3 loops * (4 * 2^20 words/loop) / (256 words/call) = 49152 calls during those ~4000 milliseconds, so the schedule() calls are still done less than 0.1ms apart. These numbers are just for a beagleboneblack, other boards may have a slower memory, but we are _two orders of magnitude_ away from schedule() "only" being called at 100Hz, which is still more than enough to ensure any watchdog is kept happy.

2025-09-02memtest: don't volatile-qualify local variablesRasmus Villemoes
It is obviously important that the addr pointer used to access the memory region being tested is volatile-qualified, to prevent the compiler from optimizing out the "write this value, read it back, check that it is what we expect". However, none of these auxiliary variables have any such need for, effectively, being forced to live on the stack and cause each and every reference to them to do a memory access. This makes the memtest about 15% faster on a beagleboneblack. Before: => dcache off => time mtest 0x81000000 0x81100000 0 1 Testing 81000000 ... 81100000: Iteration: 1 Tested 1 iteration(s) with 0 errors. time: 10.868 seconds After: => dcache off => time mtest 0x81000000 0x81100000 0 1 Testing 81000000 ... 81100000: Iteration: 1 Tested 1 iteration(s) with 0 errors. time: 9.209 seconds [Without the 'dcache off', there's no difference in the time, about 0.6s, but the memtest cannot usefully be done with dcache enabled.] Signed-off-by: Rasmus Villemoes <[email protected]> Tested-by: Anshul Dalal <[email protected]>

2024-01-17cmd/mem.c: fix wrong use of ifdef, drop pointless SUPPORT_64BIT_DATA macroRasmus Villemoes
The macro MEM_SUPPORT_64BIT_DATA is always defined, as either 1 or 0, so using "#ifdef MEM_SUPPORT_64BIT_DATA" doesn't do what one expects. This means that currently all 32 bit targets get compiled with the .q suffix mentioned in the help text, while it doesn't actually work. Use the proper "#if" instead. There's really no point defining another similarly-named macro with exactly the same value, so just use MEM_SUPPORT_64BIT_DATA throughout. Signed-off-by: Rasmus Villemoes <[email protected]>
2024-01-16cmd/mem.c: use memmove in do_mem_cp()Rasmus Villemoes
There's no 'mv' shell command for handling overlapping src and dst regions, and there's no point introducing one, when we can just make the existing 'cp' command DTRT in all cases. memmove() should at most be a few instructions more then memcpy() (to detect the appropriate direction to do the copy), which is of course completely in the noise with all the string processing that a shell command does.

A large number of files include <flash.h> as it used to be how various SPI flash related functions were found, or for other reasons entirely. In order to migrate some further CONFIG symbols to Kconfig we need to not include flash.h in cases where we don't have a NOR flash of some sort enabled.

2020-09-18cmd: mem: fix range of bitflip testRalph Siemsen
The bitflip test uses two equal sized memory buffers. This is achieved by splitting the range of memory into two pieces. The address of the second buffer, as well as the length of each buffer, were not correctly calculated. This caused bitflip test to access beyond the end of range. This patch fixes the pointer arithmetic problem. A second problem arises because u-boot "mtest" command expects the ending address to be inclusive. When computing (end - start) this results in missing 1 byte of the requested length. The bitflip test expects a count rather than an "ending" address. Thus it fails to test the last word of the requested range. Fixed by using (end - start + 1). Added Kconfig option to optionally disable the bitflip test, since it does add significantly to the time taken for "mtest".

2020-05-08cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mappingMichal Simek
There is no real need to exactly define space for saving patterns for alternate memory test. It is much easier to allocate space on the stack and use it instead of trying to find out space where pattern should be saved. For example if you want to test the whole DDR memory you can't save patter to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses were chosen but that means that OCM needs to be mapped and U-Boot has access permission there. It is easier to remove this limitation and simply save it on stack because it is very clear that memory test can't rewrite U-Boot and U-Boot has also full access to memory where runs from.

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 <[email protected]>
