2019-05-21powerpc: Simplify processor.hMario Six
Lots of stuff in processor.h was taken verbatim from the Linux kernel. It was never synced, so most of it was removed or changed in the kernel since it was imported. Remove all the stuff that is unused in the current U-Boot sources; should anybody feel the need to re-sync with the kernel, they can do it later on. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Use pre-defined asm functionsMario Six
For a lot of inline assembly calls in the mpc8xxx and mpc83xx directories, we already have convenient pre-defined helper functions, but they're not used, resulting in hard-to-read code. Use these helper functions where ever possible and useful. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Replace ppcDWstore with inline assemblyMario Six
ppcDWstore/ppcDWload are hardly used by any board, but since they're implemented in start.S, they're always present in every U-Boot image, even if they're not needed. Re-implement these fuctions in C with inline assembly, so that the compiler can decide when to actually include them. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Don't define cpu_eth_init for DM ethMario Six
Don't use the legacy method of initializing the ethernet controller on MPC83xx when DM is active. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Add arch clock.h to make SDHC workMario Six
The fsl-esdhc driver can be used for the SDHC functionality on MPC83xx, but it needs some additional definitions. Add a clock.h file, so we can use the driver for MPC83xx. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Get rid of CONFIG_SYS_DDR_SDRAM_BASEMario Six
CONFIG_SYS_DDR_SDRAM_BASE is set to the same value as CONFIG_SYS_SDRAM_BASE on all existing boards. Just use CONFIG_SYS_SDRAM_BASE instead. Signed-off-by: Mario Six <mario.six@gdsys.cc>

2019-05-21mpc83xx: Migrate CONFIG_SYS_{BR, OR}*_PRELIM to KconfigMario Six
Migrate the BR/OR settings to Kconfig. These must be known at compile time, so cannot be configured via DT. Configuration of this crucial variable should still be somewhat comfortable. Hence, make its fields configurable in Kconfig, and assemble the final value from these. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Migrate LBLAW_* to KconfigMario Six
The LBLAW_* values determine the window configuration of the memory controller. Hence, they must be known at compile time, and cannot be implemented in the DT mechanism. Configuration of this crucial variable should still be somewhat comfortable. Hence, make its fields configurable in Kconfig, and assemble the final value from these. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Migrate BATS config to KconfigMario Six
The BATs (block address translation registers) determine the initial memory window mappings. Hence, they must be known at compile time and cannot be implemented in the DT mechanism. Configuration of this crucial variable should still be somewhat comfortable. Hence, make its fields configurable in Kconfig, and assemble the final value from these.

2019-05-21mpc83xx: pcie: Read the clock from registersMario Six
The MPC83xx DM timer driver disables arch.pciexp*_clk, and uses clk_get_rate instead. But the legacy MPC83xx PCIe driver still uses arch.pciexp*_clk for the clock. Hence, read the PCIe clock from the registers in the legacy MPC83xx PCIe driver. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Kconfig: Migrate HRCW to KconfigMario Six
The HRCW (hardware reset configuration word) is a constant that must be hard-coded into the boot loader image. So, it must be available at compile time, and cannot be migrated to the DT mechanism, but has to be kept in Kconfig. Configuration of this crucial variable should still be somewhat comfortable. Hence, make its fields configurable in Kconfig, and assemble the final value from these. 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>
2019-05-21mpc83xx: Replace CONFIG_83XX_CLKIN in calculationsMario Six
CONFIG_SYS_CLK_FREQ is the standard way to set the system clock frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose. Hence, the obvious way is to replace CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ. A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing CONFIG_SYS_NS16550_CLK. This makes it harder to replace CONFIG_83XX_CLKIN. But the value of the multiplicator can be read from the SPMR register. Hence, replace the static calculations with a call to a new get_bus_freq function, as other architectures do. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Migrate legacy PCI options to KconfigMario Six
The MPC83xx include files contain some settings of the PCI subsystem. Migrate these to Kconfig until a proper DM PCI driver exists. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Make distinct MPC8349EMDS_SDRAM boardMario Six
The MPC8349EMDS config file contains config options to enable SDRAM support. To keep this ability after the Kconfig migration, create a new MPC8349EMDS_SDRAM board that enables the SDRAM support and remove the SDRAM support from the original board. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-20powerpc: Add LSDMR config valuesMario Six
The LSDMR_* macros are used to configure the system bus on MPC83xx. A few of the possible LSDMR_* macros were never defined in the respective include files. This renders the SDRAM support on the MPC8349EMDS unusable, because it uses these undefined macros. To make the SDRAM option work, introduce these macros into the proper config file. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-20mpc83xx: Make distinct caddy2 configMario Six
vme8349.h contains two separate boards: The vme8349 itself, and the caddy2 board. The caddy2 board is chosen by setting certain config variables. Create a proper config file for the caddy2 board to make Kconfig migration easier. Furthermore, simplify the vme8349 and caddy2 configs by keeping only the options necessary for each board. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-20mpc83xx: Make distinct MPC8313ERDB targetsMario Six
MPC8313ERDB has the option of either enabling NOR or NAND boot in its config file (by commenting out certain #ifdefs). To keep this ability after migrating options to Kconfig, we introduce two MPC8313ERDB configs: one for NOR, and one for NAND. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-20keymile: Make distinct kmeter1, and kmcoge5ne configsMario Six

The kmsupx5, tuge1, kmopti2, and kmtepr2 boards all build from the same include config file with lots of #ifdef logic. To ease Kconfig migration, create new config include files for these boards, and resolve the #ifdef logic as needed. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-20keymile: Make distinct kmtegr1, kmvect1, suvd3 configsMario Six
The kmtegr1, kmvect1, and suvd3 boards all use the same config include file with lots of #ifdefs in it. The Kconfig migation will become easier if we get rid of these #ifdefs first. Hence, create distinct config include files for these boards, and unwind the #ifdef logic in these config files to only include the options necessary for each board.

2019-05-18CONFIG_SYS_[DI]CACHE_OFF: convert to KconfigTrevor Woerner
CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig parameters; only for the ARC architecture. This patch turns these two parameters into Kconfig items everywhere else they are found. All of the include/configs/* and defconfig changes in this patch are for arm machines only. The Kconfig changes for arc, nds32, riscv, and xtensa have been included since these symbols are found in code under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined include/configs/* or defconfigs for these architectures exist which include these symbols. These results have been confirmed with tools/moveconfig.py.

2019-05-18CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' caseTrevor Woerner
According to De Morgan's Law[1]: !(A && B) = !A || !B !(A || B) = !A && !B There are 5 places in the code where we find: #if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) and 4 places in the code where we find: #if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)) In words, the construct: !defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE on?" and the construct: defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE off?" Therefore !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) means: "the opposite of 'are they both off?'" in other words: "are either or both on?" and: (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF) means: "are either or both on?" As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for consistency. [1] https://en.wikipedia.org/wiki/De_Morgan%27s_laws Signed-off-by: Trevor Woerner <trevor@toganlabs.com>
