* Add support for 16 MB flash configuration of TRAB board * Patch by Erwin Rol, 27 Feb 2003: Add support for RTEMS * Add image information to README * Fix dual PCMCIA slot support (when running with just one slot populated) * Add VFD type detection to trab board * extend drivers/cs8900.c driver to synchronize ethaddr environment variable with value in the EEPROM * Start adding MIPS support files

/*
Make getenv() work before relocation. So far, getenv() would work before relocation is most cases, even though it was not intended to be used that way. When switching to a hash table based implementation, this would break a number of boards. For convenience, we make getenv() check if it's running before relocation and, if so, use getenv_f() internally. Note that this is limited to simple cases, as we use a small static buffer (32 bytes) in the global data for this purpose. For this reason, it is also not a good idea to convert all current uses of getenv_f() into getenv() - some of the existing use cases need to be able to deal with longer variable values, so getenv_f() is still needed and recommended for use before relocation.

Add architecture-specific global data We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain.

struct arch_global_data {
MIPS: Support dynamic I/O port base address The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

MIPS: Probe cache line sizes once during boot Rather than probing the cache line sizes on every call of any cache maintenance function, probe them once during boot & store the values in the global data structure for later use. This will reduce the overhead of the cache maintenance functions, which isn't a big deal yet but becomes more important once L2 caches which may expose their properties via coprocessor 2 or the CM are supported.

* Implement new mechanism to export U-Boot's functions to standalone applications: instead of using (PPC-specific) system calls we now use a jump table; please see doc/README.standalone for details * Patch by Dave Westwood, 24 Jul 2003: added support for Unity OS (a proprietary OS)
