[Haret-devel] kernel size > 5MB

[Lukas Gorris]

Hello,

recently we added a new testing branch for the htc leo kernel. It has
lots of debugging stuff and the resulting Image is > 5MB. (We use non
gzipped Image because zImage will crash the qsd8250 kernel). This is
overwritten by initrd. With the appended patch applied (thanks to
Martijn aka NetRipper) there is enough room for the kernel. There are
two questions:

1) Is it useful to implement such a 'big kerne' patch?
2) If so, how should it be done? NetRipper proposed to create an
environment variable for the initrd offset.
