I can see why Philips may not be in a position to acceed to this request:

1/  This requires hardware change to flash blocking.

2/  The boot sectors (I have seen) appear pretty full.

Unless they radically change their boot loader structure to something
like SILL (which is 2600 bytes), they are not likely to be able to get
their boot loader down in size without removing a lot of (extraneous?)
functionality.

PS:  I am not saying the request is unreasonable.  I just cannot see
how it can be met if LPC boot loader structure is to be retained.
