[Clfs-support] Desire for updated ARM book-contribution

[Tom Willhite]

Hi Andrew.  Ty for the reply.   Glad to see there's one person around at least.   I am currently building PiLFS on my Rock64.    He has 2 versions; one armv7-32bit one aarch64-64 bit.    See how this goes.

I'm kind of surprised he hasn't mentioned any interest on his website about improving-contributing here,  He does give a credit.    My guess is he's into raspian pretty heavy.   I'm not much of a writer-editor but I can do build book testing and experiemtal builds like this one.    That gives me alot of ideas for book edits-entries.    I'll post back after this build fails or succeeds.

My immediate goal has been accomplished of getting a full KDE Plasma Wayland running Wayland EGL instead of Xorg using the latest mainline kernel 5.4.x and Lima drivers for the rock64 mali-450 gpu.  It runs/looks ok but its early in the way of driver functionality so it crashes quite easily.

I only have time atm for that platform but i'm sure whatever I can get done on this board is transferable to others like armv7 and older book steps wise.

There's demand but few up to date guides on building a baremetal x86-64 to armv8 cross-compiler.  Guys at Arch want it because they the devs use a slow qemu VM to build on or a farm of arm boards.

I don't know that a lot of armv8 work has been done yet for CLFS, but
if you'd like to contribute then I think it would be welcomed!

I don't personally have much experience with armv8, but if you want
any changes pulled into the embedded CLFS book, please feel free to
fork the embedded book github repo and send a pull request and I'll
have a look at it.  The OE/Yocto Project recipes as well as Buildroot
scripts should give some good direction on what's needed for a 32/64
bit armv8 toolchain which may be helpful.

CLFS development has definitely slowed in recent times, but it still
moves forward when people have time and energy.
Thanks,
Andrew
