You can see the example in OvmfPkgIa32.fdf.
FILE FV_IMAGE = A4EF5A93-3F1B-4232-A1C4-F0910E6D1D9C {
SECTION COMPRESS PI_NONE { ## here PI_NONE should be changed to PI_STD
for compression.
SECTION FV_IMAGE = DXEFV
}
}
Thanks

Andrew,
Thanks. Yes compressing FV equally good solution for me; Where can I find
syntax to compress the entire FV?
Thanks

Alok,
On a side note, you usually get better compression if you compress the entire
FV. A file in the FV can contain a compressed FV. This could be another
workaround.
