      ichspi: use a variable to distinguish ich generations instead of spi_programmer->type · a8d838d9
      Stefan Tauner authored 
      
The type member is enough most of the time to derive the wanted
information, but
 - not always (e.g. ich_set_bbar),
 - only available after registration, which we want to delay till the
   end of init, and
 - we really want to distinguish between chipset version-grained
   attributes which are not reflected by the registered programmer.

Hence this patch introduces a new static variable which is set up
early by the init functions and allows us to get rid of all "switch
(spi_programmer->type)" in ichspi.c. We reuse the enum introduced
for descriptor mode for the type of the new variable.

Previously magic numbers were passed by chipset_enable wrappers. Now
they use the enumeration items too. To get this working the enum
definition had to be moved to programmer.h.

Another noteworthy detail: previously we have checked for a valid
programmer/ich generation all over the place. I have removed those
checks and added one single check in the init method. Calling any
function of a programmer without executing the init method first, is
undefined behavior.

      ichspi: add ICH/PCH flash descriptor decoding via FDOC/FDOD · 1e14639f
      Stefan Tauner authored 
      Based on the work of Matthias 'mazzoo' Wenzel this patch adds pretty
printing of those ICH/PCH flash descriptor sections that are
cached/mapped by the chipset (and which are therefore reachable via
FDOC/FDOD registers).

this includes the following:
- content section:
    describes the image and some generic properties (number of
    sections, offset of sections, PCH/ICH and MCH/PROC strap
    offsets and lengths)
- component section:
    identify the different SPI flash chips and their capabilities.
- region section
    similarly to a partition table this describes the different regions.
    the content of FLREG* is derived from this section.
- master section
    defines SPI master (host, ME, GbE) access rights of the
    individual regions. the content of PR* is derived from this section.

this is only a part of the data included in the descriptor. other
information can be retrieved from a complete binary dump of the
descriptor region only.

      serprog: add SPI support · c93f5f12
      Urja Rannikko authored 
      
Adds a new opcode (0x13) that just relays SPI bytes and wires it up to be
usable within serprog.c. Checks for mandatory opcodes are moved around and
changed a bit, but non-SPI programmers should not be harmed by this patch.
