* | Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass2016-03-14-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

* powerpc/km8321: define CONFIG_SYS_DDRCDRValentin Longchamp2015-11-18-0/+6
| | | | | | | | | | | | | | | | | | | | | | On the km8321 boards is CONFIG_SYS_DDRCDR not defined, which leads to the DDRCDR not being configured at startup and still containing the reset value. The required settings for our km8321 hardware designs are different than the reset value and must be set with CONFIG_SYS_DDRCDR, that is used by mpc83xx's cpu_init_f function at early CPU initialization. The important settings are the DDR2 internal voltage level and the half-strength "drivers". In our case where the DRAM chips are soldered on board and the routing for these signals under control, half-strength is sufficient as a few measurements done in the lasts have shown. Since all the hardware qualification tests have been performed with half strength, the nominal strength settings are removed in favor of the default reset half strength settings.

* km: update the boot script to check for a DTBValentin Longchamp2015-11-18-2/+11
| | | | | | | | | | | | | | If a DTB is found with cramfsls, the bootscript continues as expected. If none is found, the cramfsloadfdt and boot subbootcmds are updated to not load the DTB from cramfs and not pass it to the kernel. The kernel thus must have an appended DTB otherwise the boot will fail. This is required for the km_kirkwood boards that must support .esw where the DTB sometimes is appended (for backwards compatibility) and sometimes is passed correctly (as we do now for all newer boards).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add set_fdthigh subcommand to "subbootcmds" (release) so to set "fdt_high" This is necessary on Kirkwood so that the FDT does not get relocated above the memory limit that the kernel cannot access (that is the memory part reserved for the switch). This was tested on NUSA1, where it is necessary, and on ETER1, where it doesn't seem to hurt. We want the scripts to also work with older versions of u-boot, where: a) set_fdthigh is not defined (will be default env for newer u-boots) b) the fdt will not be available For this reason, we use "set_fdthigh" to tell whether we are running a newer (FDT-aware) u-boot or not. So if "set_fdthigh" runs successfully or arch != arm we try loading the fdt; otherwise we proceed normally. Notice how, contrary to release mode, set_fdthigh will _not_ be part of subbootcmds for develop and ramfs, but will be executed as part of "tftpfdt". Since this is only needed for kirkwood cards, and it prevents the kernel from booting on QorIQ (though it seemed to work on ETER1), we change its definition in the default env for powerpc so that the value is only set on ARM.
