[Avila] Maximum dimension of zImage

[Gianluca Mando]

Hi Emre,

If I use the command:

"load -r -b %{FREEMEMLO} zImage"

what is the command to burn on flash the zImage? Actually I'm using

"fis create -e 0x01600000 -r 0x0160000 zimage"

taking as reference the RAM address 0x01600000.

Regarding the size of the zImage I think that it should bigger than 1.1 MB.
Actually I use a kernel of 1.5 MB compressed and have no problem.

Thank you

Gianluca
