From 5de0d1e9392bde4665ddb6cd216400e832b8178c Mon Sep 17 00:00:00 2001 From: mkarcher Date: Wed, 11 May 2011 17:07:07 +0000 Subject: kill central list of SPI programmers Remove the array spi_programmer, replace it by dynamic registration instead. Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").
