board: cssi: Add new board MCR3000_2G

2023-02-11T07:47:58Z

This adds a new board from CS GROUP. The board is called MCR3000_2G, and has a CPU board called CMPC885. That CPU board is shared with another equipment that will be added in a later patch. That board stores Ethernet MAC addresses in an EEPROM which is accessed using SPI bus. This patch was originally written by Charles Frey who's email address is not valid anymore as he left the company. Signed-off-by: Christophe Leroy Reviewed-by: FRANJOU Stephane

board: MCR3000: Use lowercase filenames

2023-02-10T18:33:25Z

Rename MCR3000.* to mcr3000.* to be more in line with other boards. Signed-off-by: Christophe Leroy

powerpc/mpc8xx: Zero boot_flags arg for calling board_init_f()

2023-02-10T18:31:36Z

Copied from e83a7e94532 ("powerpc/mpc83xx: Zero boot_flags arg for calling board_init_f()") The argument boot_flags of board_init_f() is not used at all in the powerpc specific board.c init sequence. Now with the generic init sequence, this boot_flags arg is used by board_init_f(). This patch sets the r3 register that is used to pass the boot_flags argument from the start.S board_init_f() call to 0 prior to the function call to avoid unknown content to end up in gd->flags.

global: Finish CONFIG -> CFG migration

2023-01-20T17:27:24Z

At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

nxp: Finish migration of SYS_FSL_SRDS_[12] to Kconfig

2023-01-20T17:27:23Z

As this is used on both ARM and PowerPC platforms, this needs to be listed in arch/Kconfig.nxp and match how they're currently used by select'ing them under the required PowerPC ARCH_xxx options. Signed-off-by: Tom Rini

global: Remove unused CONFIG defines

2023-01-20T17:27:06Z

Remove some CONFIG symbols and related comments, etc, that are unused within the code itself at this point. Signed-off-by: Tom Rini

event: Correct dependencies on the EVENT framework

2023-01-18T17:46:13Z

The event framework is just that, a framework. Enabling it by itself does nothing, so we shouldn't ask the user about it. Reword (and correct typos) around this the option and help text. This also applies to DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be visible to the user to select, when EVENT is selected. With this, it's time to address the larger problems. When functionality uses events, typically via EVENT_SPY, the appropriate framework then must be select'd and NOT imply'd. As the functionality will cease to work (and so, platforms will fail to boot) this is non-optional and where select is appropriate. Audit the current users of EVENT_SPY to have a more fine-grained approach to select'ing the framework where used. Also ensure the current users of event_register and also select EVENT_DYNAMIC.

powerpc/mpc85xx: socrates: Re-enable building u-boot-socrates.bin

2023-01-06T13:14:19Z

U-Boot build system builds final U-Boot binary for socrates board in custom file u-boot-socrates.bin (instead of standard u-boot.bin). Output target file u-boot-socrates.bin is generated by binman as defined in board binman config file arch/powerpc/dts/socrates-u-boot.dtsi. But binman was disabled in commit 5af42eafd7e1 ("Makefile: Reduce usage of custom mpc85xx u-boot.bin target") for all mpc85xx boards which do not use standard powerpc binman config file arch/powerpc/dts/u-boot.dtsi and boards which do not require binman at all. The only such mpc85xx board is socrates. So since that commit, U-Boot does not final binary for socrates board anymore. Fix this issue by re-enabling binman for socrates board. And build process starts again producing u-boot-socrates.bin binary. Note that build process for this socrates board always produce u-boot.bin binary which is broken and not usable for socrates board. Long term solution should be to disable building broken binary u-boot.bin and then renaming u-boot-socrates.bin to u-boot.bin, or switching to use common powerpc binman config file arch/powerpc/dts/socrates-u-boot.dtsi (if it is possible).

PowerPC: Update dependencies on *SYS_MPC85XX_NO_RESETVEC

2022-12-29T18:31:30Z

In 96699f097a02 ("powerpc: mpc85xx: Use binman to embed dtb inside U-Boot") we introduce CONFIG_MPC85XX_HAVE_RESET_VECTOR and do so via Kconfig. However, much later in de47ff536363 ("Convert CONFIG_SYS_MPC85XX_NO_RESETVEC to Kconfig") I converted the symbol that is the inverse of this to Kconfig. This should have included a dependency on the first symbol as they are logically opposite. The dependency being missing lead to some platforms being broken at runtime due to discarding the require reset vector.
