-
- Define this to measure the actual CPU clock instead
- of relying on the correctness of the configured

- (like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
- CONFIG_8xx_CONS_SCC1, ...), or switch off the serial
- console by defining CONFIG_8xx_CONS_NONE
-

the maximum receive buffer length for the SMC.
- This option is actual only for 82xx and 8xx possible.

CONFIG_SYS_JFFS2_FIRST_BANK, CONFIG_SYS_JFFS2_NUM_BANKS

the malloc area (as defined by CONFIG_SYS_MALLOC_LEN) should
be at least 4MB.
- CONFIG_LZMA
-
- If this option is set, support for lzma compressed
- images is included.
-
- Note: The LZMA algorithm adds between 2 and 4KB of code and it
- requires an amount of dynamic memory that is given by the
- formula:
-
- (1846 + 768 << (lc + lp)) * sizeof(uint16)
-
- Where lc and lp stand for, respectively, Literal context bits
- and Literal pos bits.
-
- This value is upper-bounded by 14MB in the worst case. Anyway,
- for a ~4MB large kernel image, we have lc=3 and lp=0 for a
- total amount of (1846 + 768 << (3 + 0)) * 2 = ~41KB... that is
- a very small buffer.
-
- Use the lzmainfo tool to determinate the lc and lp values and
- then calculate the amount of needed dynamic memory (ensuring
- the appropriate CONFIG_SYS_MALLOC_LEN value).
-

on those systems that support this (optional)
- feature, like the TQM8xxL modules.

- If defined, specifies the I2C address of the DTT device.
- If not defined, then U-Boot uses predefined value for
- specified DTT device.
