can be displayed via the splashscreen support or the
bmp command.
-- Compression support:
- CONFIG_GZIP
-
- Enabled by default to support gzip compressed images.
-
- CONFIG_BZIP2
-
- If this option is set, support for bzip2 compressed
- images is included. If not, only uncompressed and gzip
- compressed images are supported.
-
- NOTE: the bzip2 algorithm requires a lot of RAM, so
- the malloc area (as defined by CONFIG_SYS_MALLOC_LEN) should
- be at least 4MB.
-
- MII/PHY support:
CONFIG_PHY_CLOCK_FREQ (ppc4xx)
This enable the NEW i2c subsystem, and will allow you to use
i2c commands at the u-boot command line (as long as you set
- CONFIG_CMD_I2C in CONFIG_COMMANDS) and communicate with i2c
- based realtime clock chips or other i2c devices. See
- common/cmd_i2c.c for a description of the command line
- interface.
-
- ported i2c driver to the new framework:
- - drivers/i2c/soft_i2c.c:
- - activate first bus with CONFIG_SYS_I2C_SOFT define
CONFIG_SYS_I2C_SOFT_SPEED and CONFIG_SYS_I2C_SOFT_SLAVE
for defining speed and slave address
- activate second bus with I2C_SOFT_DECLARATIONS2 define
- CONFIG_SYS_BAUDRATE_TABLE:
List of legal baudrate settings for this board.
-- CONFIG_SYS_MEMTEST_START, CONFIG_SYS_MEMTEST_END:
- Begin and End addresses of the area used by the
- simple memory test.
-
-- CONFIG_SYS_MEMTEST_SCRATCH:
- Scratch address used by the alternate memory test
- You only need to set this if address zero isn't writeable
-
- CONFIG_SYS_MEM_RESERVE_SECURE
Only implemented for ARMv8 for now.
If defined, the size of CONFIG_SYS_MEM_RESERVE_SECURE memory
regular expression. This allows multiple variables to define the same
flags without explicitly listing them for each variable.
-- CONFIG_ENV_ACCESS_IGNORE_FORCE
- If defined, don't allow the -f switch to env set override variable
- access flags.

The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
