2019-12-03bootm: vxworks: Support Linux compatible standard DTB for ARM and PPCLihua Zhao
Enhance do_bootm_vxworks() to support Linux compatible standard DTB for ARM and PPC, when the least significant bit of flags in VxWorks bootargs is set. Otherwise it falls back to the existing bootm flow which is now legacy.

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>
2018-04-16bootvx: x86: Assign bootaddr based on kernel memory baseBin Meng
On VxWorks x86 its bootline address is at a pre-defined offset @ 0x1200. If 'bootaddr' is not passed via environment variable, we assign its value based on the kernel memory base address. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
2018-04-16bootvx: x86: Make VxWorks EFI console driver happyBin Meng
When booting from EFI BIOS, VxWorks bootloader stores the EFI GOP framebuffer info at a pre-defined offset @ 0x6100. When VxWorks kernel boots up, its EFI console driver tries to find such a block and if the signature matches, the framebuffer information will be used to initialize the driver. However it is not necessary to prepare an EFI environment for VxWorks's EFI console driver to function (eg: EFI loader in U-Boot). If U-Boot has already initialized the graphics card and set it to a VESA mode that is compatible with EFI GOP, we can simply prepare such a block for VxWorks.

2018-04-16bootvx: x86: Explicitly clear the bootloader image sizeBin Meng
VxWorks bootloader stores its size at a pre-defined offset @ 0x5004. Later when VxWorks kernel boots up and system memory information is retrieved from the E820 table, the bootloader size will be subtracted from the total system memory size to calculate the size of available memory for the OS. Explicitly clear the bootloader image size otherwise if memory at this offset happens to contain some garbage data, the final available memory size for the kernel is insane.

2018-04-16bootvx: x86: Prepare e820 related stuff from the given kernel memory base ↵Bin Meng
address At present two environment variables 'e820data'/'e820info' are required to boot a VxWorks x86 kernel, but this is superfluous. The offset of these two tables are actually at a fixed offset from the kernel memory base address and we can provide the kernel memory base address to U-Boot via only one variable 'vx_phys_mem_base'. Note as it name indicates, the physical address should be provided. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2015-10-21cmd: bootvx: Always get VxWorks bootline from envBin Meng
So far VxWorks bootline can be contructed from various environment variables, but when these variables do not exist we get these from corresponding config macros. This is not helpful as it requires rebuilding U-Boot, and to make sure these config macros take effect we should not have these environment variables. This is a little bit complex and confusing. Now we change the logic to always contruct the bootline from environments (the only single source), by adding two new variables "bootdev" and "othbootargs", and adding some comments about network related settings mentioning they are optional. The doc about the bootline handling is also updated. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com> Tested-by: Hannes Schmelzer <oe5hpm@oevsv.at>

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
