@ -1723,29 +1723,6 @@ The following options need to be configured:
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).
CONFIG_LZO
If this option is set, support for LZO compressed images
