| * | | MIPS: BCM47XX: use fallback sprom var for board_{rev,type}Hauke Mehrtens2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An SoC normally do not define path variables for board_rev and board_type and the Broadcom SDK also uses the nvram values without a prefix in such cases. Do the same to fill these sprom attributes from nvram and do not leave them empty, because brcmsmac do not like this.

There is just 32KB space for the nvram, but most devices do not use the full size and this code reads the first 32KB in that case and prints a warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are bcma based devices like the Linksys E2000 out there, which do have one ieee80211 core, but no PCIe core and they are using no prefixes for the sprom. In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices. The Ethernet addresses are now also read out correctly without a prefix so calling bcm47xx_fill_sprom_ethernet is not needed any more.

Currently we are just checking when the function prom_init is seen again, but it is better to check for a bigger part of the memory to decrease the chance of wrong results.

| | | | | | | | | | | | Nvram_getenv should behave like cfe_getenv. cfe_getenv returns 0 on success and -9 if the value was not found. If the input was wrong -8 will be returned by cfe_getenv. Change nvram_getenv to do the same.

* MIPS: BCM47xx: Really fix 128MB RAM problemHauke Mehrtens2010-08-05
| | | | | | | | | | | | | | | | | | | The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp. 84a6fcb368a080620d12fc4d79e07902dbee7335 (kernel.org) was wrong. The BCM47xx architecture maps the ram into a 128MB address space. It will be spaced there as often as goes into the 128MB. Detection tries to find the position where the same memory is found. When reading beyond 128MB the processor will throw an exception. If 128MB RAM is installed, it will not find a memory alias because it tries to read beyond the 128MB border. Now it just assumes 128MB installed ram if it can not find an alias.
