2024-12-30Merge patch series "Misc. PowerPC MPC83xx fixes/cleanups"Tom Rini
J. Neuschäfer <j.ne@posteo.net> says: This patchset contains a few small fixes/cleanups for the MPC83xx platform. Link: https://lore.kernel.org/r/20241220-mpc83xx-misc-v2-0-ff4c17ee5fa4@posteo.net
2024-12-30powerpc: mpc83xx: Use defined constant for SPCR[TBEN]J. Neuschäfer
To increase readability, use the defined constant instead of specifying SPCR[TBEN] as a number. Reviewed-by: Sinan Akman <sinan@writeme.com> Signed-off-by: J. Neuschäfer <j.ne@posteo.net>
2024-12-30powerpc: mpc83xx: Allow including initreg.h into multiple filesJ. Neuschäfer
Globals defined in headers can result in multiple-definition errors while linking, if they are visible beyond the current translation unit. This hasn't been a problem for initreg.h so far, but would become a problem in the next patch, where I use a constant from initreg.h in a second C file.

2024-12-30powerpc: Fix 0 vs. r0 confusion in X/D-form instructionsJ. Neuschäfer
Instructions such as dcbi are in the X-form; they have RA and RB fields and the effective address (EA) is computed as (RA|0)+(RB). In words, this means that if RA is zero, the left-hand side of the addition is zero, otherwise the corresponding GPR is used. r0 can never be used on the left-hand side of a X-form instruction. For D-form instructions such as addis, the Power ISA illustrates this in the instruction pseudo-code: if RA = 0 then RT <- EXTS(SI || 0x0000) else RT <- (RA) + EXIS(SI || 0x0000) In all of these cases, RA=0 indicates the value zero, not register r0. I verified with gazerbeam_defconfig (MPC83xx) and qemu-ppce500_defconfig (MPC85xx) that this patch results in the same machine code. Signed-off-by: J. Neuschäfer <j.ne@posteo.net>

2023-04-06powerpc: mpc83xx: Don't activate MMU when not necessaryChristophe Leroy
At startup, some RAM is needed (for instance for stack) before DRAM is initialised. One way to offer such RAM, used by mpc83xx, is to lock some entries in the cache. To do that, MMU needs to be activated. On mpc83xx having a QUICC Engine an alternative is to user some part of from the Multi User RAM, like done on mpc8xx for instance. For that, the MMU is not needed. Activating the MMU is problematic because exception vectors are not setup yet so in case of ISI or DSI that CPU will crash and reboot. At the time being, MMU is activated regardless. Only activate it when locking cache entries to provide initial RAM. Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu>

2022-06-23linker_lists: Rename sections to remove . prefixAndrew Scull
Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

2022-04-01keymile: Move sourcing of common KconfigTom Rini
The way board/keymile/Kconfig is written protects the options there from being parsed on non-keymile platforms. We cannot however safely source this file from multiple locations. This does not manifest as a problem currently as there are no choice statements inside of this file (nor the sub-Kconfig files it sources). However, moving some target selection to one of these files exposes the underlying problem. Rework things so that we have this file sourced in arch/Kconfig.

2021-12-27Finish conversion of CONFIG_SYS_CLK_FREQ to KconfigTom Rini
In order to finish moving this symbol to Kconfig for all platforms, we need to do a few more things. First, for all platforms that define this to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk() and updating a few preprocessor tests. With that done, all platforms that define a value here can be converted to Kconfig, and a fall-back of zero is sufficiently safe to use (and what is used today in cases where code may or may not have this available). Make sure that code which calls this function includes <clock_legacy.h> to get the prototype. Signed-off-by: Tom Rini <trini@konsulko.com>
