Fix SPI build errors in exports.c The spi.h include is no longer included in exports.h, so must be included here. This fixes these errors: In file included from exports.c:41:0: /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h: In function 'jumptable_init': /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:27:1: error: 'spi_init' undeclared (first use in this function) /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:27:1: note: each undeclared identifier is reported only once for each function it appears in /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:28:1: error: 'spi_setup_slave' undeclared (first use in this function) /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:29:1: error: 'spi_free_slave' undeclared (first use in this function) /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:30:1: error: 'spi_claim_bus' undeclared (first use in this function) /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:31:1: error: 'spi_release_bus' undeclared (first use in this function) /home/sjg/trunk/src/third_party/u-boot/files/include/_exports.h:32:1: error: 'spi_xfer' undeclared (first use in this function) Signed-off-by: Simon Glass <sjg@chromium.org> 2011-12-06 19:31:32 +00:00			`#include <spi.h>`
Export redesign this is an atempt to make the export of functions typesafe. I replaced the jumptable void ** by a struct (jt_funcs) with function pointers. The EXPORT_FUNC macro now has 3 fixed parameters and one variadic parameter The first is the name of the exported function, the rest of the parameters are used to format a functionpointer in the jumptable, the EXPORT_FUNC macros are expanded three times, 1. to declare the members of the struct 2. to initialize the structmember pointers 3. to call the functions in stubs.c Signed-off-by: Martin Dorwig <dorwig@tetronik.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (resending to the list since my tweaks are not quite trivial) 2015-01-26 22:22:54 +00:00			`#include <i2c.h>`

exports: rewrite jump table init The current jump table init fails to initialize a bunch of exported symbols (forceenv/do_reset/etc...). Rather than fix just these few missing pieces, rewrite the code to utilize the existing list of exported symbols -- _exports.h. Since every exported symbol has to be listed in this header, it makes sense to use it so that we only ever have one list that needs to be updated and things can't fall out of sync again.
