cbfs: support concurrent media channels properly
Coreboot generic CBFS media API does not support multiple media access instances, but it should. With this fix the CBFS context (memory cache for SPI accesses) is shared among all open media access streams. A better memory management scheme might be required, but for now this fix allows to support booting deptcharge and accessing VPD through two independent CBFS media streams. BUG=chrome-os-partner:32152 TEST=no exception is thrown when the second stream is opened Change-Id: I62889089b4832c9e9760ef24ecc517220d8f3ec4 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 691f9794805d04beff349f1bc60ac9d7530d7cbf Original-Change-Id: Ib9d9d1f5209c2e515a95d7acbf4a8ac1255d3f8a Original-Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/219441 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/8897 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
