symbol should be set to the TLB1 entry to be used for this
purpose.
+ CONFIG_SYS_FSL_ERRATUM_A004510
+
+ Enables a workaround for erratum A004510. If set,
+ then CONFIG_SYS_FSL_ERRATUM_A004510_SVR_REV and
+ CONFIG_SYS_FSL_CORENET_SNOOPVEC_COREONLY must be set.
+
+ CONFIG_SYS_FSL_ERRATUM_A004510_SVR_REV
+ CONFIG_SYS_FSL_ERRATUM_A004510_SVR_REV2 (optional)
+
+ Defines one or two SoC revisions (low 8 bits of SVR)
+ for which the A004510 workaround should be applied.
+
+ The rest of SVR is either not relevant to the decision
+ of whether the erratum is present (e.g. p2040 versus
+ p2041) or is implied by the build target, which controls
+ whether CONFIG_SYS_FSL_ERRATUM_A004510 is set.
+
+ See Freescale App Note 4493 for more information about
+ this erratum.
+
+ CONFIG_SYS_FSL_CORENET_SNOOPVEC_COREONLY
+
+ This is the value to write into CCSR offset 0x18600
+ according to the A004510 workaround.
+
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
- Monitor Functions:
Monitor commands can be included or excluded
from the build by using the #include files
- "config_cmd_all.h" and #undef'ing unwanted
- commands, or using "config_cmd_default.h"
+ <config_cmd_all.h> and #undef'ing unwanted
+ commands, or using <config_cmd_default.h>
and augmenting with additional #define's
for wanted commands.
If this variable is defined, an environment variable
named "ver" is created by U-Boot showing the U-Boot
version as printed by the "version" command.
- This variable is readonly.
+ Any change to this variable will be reverted at the
+ next reset.
- Real-Time Clock:
commands like bootm or iminfo. This option is
automatically enabled when you select CONFIG_CMD_DATE .
-- Partition Support:
- CONFIG_MAC_PARTITION and/or CONFIG_DOS_PARTITION
- and/or CONFIG_ISO_PARTITION and/or CONFIG_EFI_PARTITION
+- Partition Labels (disklabels) Supported:
+ Zero or more of the following:
+ CONFIG_MAC_PARTITION Apple's MacOS partition table.
+ CONFIG_DOS_PARTITION MS Dos partition table, traditional on the
+ Intel architecture, USB sticks, etc.
+ CONFIG_ISO_PARTITION ISO partition table, used on CDROM etc.
+ CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
+ bootloader. Note 2TB partition limit; see
+ disk/part_efi.c
+ CONFIG_MTD_PARTITIONS Memory Technology Device partition table.
If IDE or SCSI support is enabled (CONFIG_CMD_IDE or
CONFIG_CMD_SCSI) you must configure support for at
- least one partition type as well.
+ least one non-MTD partition type as well.
- IDE Reset method:
CONFIG_IDE_RESET_ROUTINE - this is defined in several
can be displayed via the splashscreen support or the
bmp command.
+- Do compresssing for memory range:
+ CONFIG_CMD_ZIP
+
+ If this option is set, it would use zlib deflate method
+ to compress the specified memory at its best effort.
+
- Compression support:
CONFIG_BZIP2
29,916,167 26,005,792 bootm_start
30,361,327 445,160 start_kernel
+ CONFIG_CMD_BOOTSTAGE
+ Add a 'bootstage' command which supports printing a report
+ and un/stashing of bootstage data.
+
+ CONFIG_BOOTSTAGE_FDT
+ Stash the bootstage information in the FDT. A root 'bootstage'
+ node is created with each bootstage id as a child. Each child
+ has a 'name' property and either 'mark' containing the
+ mark time in microsecond, or 'accum' containing the
+ accumulated time for that bootstage id in microseconds.
+ For example:
+
+ bootstage {
+ 154 {
+ name = "board_init_f";
+ mark = <3575678>;
+ };
+ 170 {
+ name = "lcd";
+ accum = <33482>;
+ };
+ };
+
+ Code in the Linux kernel can find this in /proc/devicetree.
+
Legacy uImage format:
Arg Where When
CONFIG_SYS_SPL_MALLOC_SIZE
The size of the malloc pool used in SPL.
+ CONFIG_SPL_FRAMEWORK
+ Enable the SPL framework under common/. This framework
+ supports MMC, NAND and YMODEM loading of U-Boot and NAND
+ NAND loading of the Linux Kernel.
+
+ CONFIG_SPL_DISPLAY_PRINT
+ For ARM, enable an optional function to print more information
+ about the running system.
+
CONFIG_SPL_LIBCOMMON_SUPPORT
Support for common/libcommon.o in SPL binary
CONFIG_SPL_SPI_SUPPORT
Support for drivers/spi/libspi.o in SPL binary
+ CONFIG_SPL_RAM_DEVICE
+ Support for running image already present in ram, in SPL binary
+
CONFIG_SPL_LIBGENERIC_SUPPORT
Support for lib/libgeneric.o in SPL binary
Disable PCI-Express on systems where it is supported but not
required.
+- CONFIG_PCI_ENUM_ONLY
+ Only scan through and get the devices on the busses.
+ Don't do any setup work, presumably because someone or
+ something has already done it, and we don't need to do it
+ a second time. Useful for platforms that are pre-booted
+ by coreboot or similar.
+
- CONFIG_SYS_SRIO:
Chip has SRIO or not
