Press Release from Castle Technology Ltd
Mike Williams
10th February 2003
Castle Technology Limited note with interest the recent discussion
regarding their IYONIX computer, the world's first desktop computer to
use the Intel XScale processor.
Following discussions with Russell King and with this in mind, Castle
should like to respond to claims originally proposed in Justin
Fletcher's "ReadMe.txt" file and Russell King's subsequent posting to
the Linux Kernel Mailing List.
The RISC OS 5.00 kernel did not contain work taken from or derived from
the ARM-Linux or Linux kernel.
The RISC OS 5.01 kernel did not contain work taken from or derived from
the ARM-Linux or Linux kernel.
The RISC OS 5.02 kernel does not contain work taken from or derived from
the ARM-Linux or Linux kernel.
There are no plans to use GPL derived code in any part of the RISC OS
kernel in the future.
For the avoidance of doubt, the hardware abstraction layer (roughly
analogous to a PC's BIOS) has it's PCI allocation and bridge setup based
in part on the following functions from the Linux kernel sources:
pci_alloc_primary_bus
pbus_size_bridges
pbus_assign_resources_sorted
pci_setup_bridge
pci_bridge_check_ranges
pbus_size_mem
pbus_assign_resources
pci_assign_unassigned_resources
pci_scan_bus
pcibios_update_resource
pci_read_bases
pci_alloc_bus
pci_add_new_bus
pci_do_scan_bus
pci_scan_bridge
pci_setup_device
pci_scan_device
pci_scan_slot
pcibios_fixup_bus
pci_calc_resource_flags
pci_size
pdev_fixup_device_resources
pbus_assign_bus_resources
pci_do_scan_bus
pcibios_fixup_pbus_ranges
pci_assign_resource
pdev_sort_resources
pdev_enable_device
pbus_size_io
Any company or individual wishing to receive a copy of the source code
to this component should apply in writing to:
The Managing Director
Castle Technology Ltd
Ore Trading Estate
Woodbridge Road
Framlingham
Suffolk
IP13 9LL
enclosing a formatted 3.5" floppy diskette and return postage stamps, or
international reply coupons for those outside the United Kingdom.
These sources will also form an integral part of a forthcoming Linux
port to the IYONIX.
With the tough goal of fitting all of the supporting software and
applications for the IYONIX computer into just 4Mbytes of ROM, later
issues of the supporting software have had to have function names
removed (along with a strategy of tokenising textual messages and
compressing binaries) to make room for, in particular, the support for
the 'boot keyboard' USB drivers.
