MIPS: BCM47XX: remove MODULE_LICENSE in non-modules Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

firmware/nvram: bcm47xx: support init from IO memory Provide NVMEM content to the NVRAM driver from a simple memory resource. This is necessary to use NVRAM in a memory- mapped flash device. Patch taken from OpenWrts development tree. This patch makes it possible to use memory-mapped NVRAM on the D-Link DWL-8610AP and the D-Link DIR-890L.

firmware: bcm47xx_nvram: inline code checking NVRAM size Separated function was not improving code quality much (or at all). Moreover it expected possible flash end address as argument and it was returning NVRAM size. The new code always operates on offsets which means less logic and less calculations.

firmware: bcm47xx_nvram: _really_ correct size_t printf format Commit feb4eb060c3a ("firmware: bcm47xx_nvram: Correct size_t printf format") was wrong, and changed a printout of 'header.len' - which is an u32 type - to use '%zu'. It apparently did pattern matching on the other case, where it printed out 'nvram_len', which is indeed of type 'size_t'. Rather than undoing the change, this just makes it use the variable that the change seemed to expect to be used.

drivers/firmware/broadcom/bcm47xx_nvram.c: fix incorrect __ioread32_copy Commit 1f330c327900 ("drivers/firmware/broadcom/bcm47xx_nvram.c: use __ioread32_copy() instead of open-coding") switched to use a generic copy function, but failed to notice that the header pointer is updated between the two copies, resulting in bogus data being copied in the latter one. Fix by keeping the old header pointer. The patch fixes totally broken networking on WRT54GL router (both LAN and WLAN interfaces fail to probe).

MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/ After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.
