From f893aeb4ed7ffb91c4074fe75ce3fe86c174567d Mon Sep 17 00:00:00 2001 From: Mark Spender Date: Thu, 16 Nov 2017 08:04:29 +0000 Subject: [PATCH] net/sfc/base: fix diagnostics support build without Siena The compilation failed because __efx_sram_pattern_fns was used in efx_nic.c, but defined in efx_sram.c which is only needed when supporting Siena. To fix it move all the code using __efx_sram_pattern_fns into Siena-specific files (except for the definition in efx_sram.c itself, as that file only needs to be included in Siena-supporting builds anyway). The functions to test registers and tables are unlikely to apply to any new hardware and so can be moved into Siena files. Since Huntington such tests have been implemented in firmware.
