2019-05-21mpc83xx: Define _end symbolMario Six
To support OF_EMBED, the MPC83xx architecture has to define the "_end" symbol to correctly access the appended DT. Fortunately, MPC8xx already defines the symbol, and the linker script is quite similar to that of MPC83xx, so copy this approach for MPC83xx. 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>

Replace the hard-coded CONFIG_SYS_NS16550_CLK value for the FDT fixup with the previously introduced get_serial_clock function This will make it possible to activate DM for serial devices on MPC83xx later on. Signed-off-by: Mario Six <mario.six@gdsys.cc>
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: 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. Signed-off-by: Mario Six <mario.six@gdsys.cc>
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

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>
2019-05-20mpc83xx: 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 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.

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>

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.
