Realtek NIC (8169)
by Mark Brown 08 Mar '12

08 Mar '12

Wonder if there is a way to support the RTL8169 chipset, for SPI based programming. Very common and inexpensive card. Would be wonderful to support something like gPXE/iPXE PXE ROMs on those NICs. The typical 128kbit SPI rom/eprom/prom variations are often ATMEL or like. e.f. ATMEL518 93C64 Marc

Author: mkarcher Date: Tue Mar 6 23:17:06 2012 New Revision: 1513 URL: http://flashrom.org/trac/flashrom/changeset/1513 Log: Prevent submission of empty read requests in linux_spi. The submission of zero-sized read requests in a write-only transaction fails at least for omap2_mcspi drivers and is pointless in general. This patch does not address the implementation of zero-sized writes (which would need to skip the write command), as there are no flash transactions not starting with a command.
