2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-01-17common: Move clock functions into a new fileSimon Glass
These three clock functions don't use driver model and should be migrated. In the meantime, create a new file to hold them. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-12-02Move strtomhz() to vsprintf.hSimon Glass
At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2019-05-21powerpc: mpc83xx: Implement get_serial_clock()Mario Six
DM serial drivers on PowerPC determine their clock frequency via the get_serial_clock function. This function is not Implemented yet for MPC83xx. This patch Implements the function so that DM serial drivers work on MPC83xx. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Get rid of CONFIG_83XX_CLKINMario Six
MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the system clock. To migrate the architecture, we can replace CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ. To do this * replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ * set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all MPC83xx config files Signed-off-by: Mario Six <mario.six@gdsys.cc>

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>

2011-09-29powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun
Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

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) { ...

As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure.
