2017-01-18ARM: dts: BCM5301X: Specify all RAM by including an extra blockRafał Miłecki1-1/+2
The first 128 MiB of RAM can be accessed using an alias at address 0x0. In theory we could access whole RAM using 0x80000000 - 0xbfffffff range (up to 1 GiB) but it doesn't seem to work on Northstar. For some reason (hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff range can't be used. I reproduced this problem on: 1) Buffalo WZR-600DHP2 (BCM47081) 2) Netgear R6250 (BCM4708) 3) D-Link DIR-885L (BCM47094) So it seems we're forced to access first 128 MiB using alias at 0x0 and the rest using real base address + 128 MiB offset which is 0x88000000.

2016-10-19ARM: BCM5301X: Enable UART on Netgear R8000Rafał Miłecki1-1/+1
It was tested by LEDE users, all we need is to adjust clock frequency. While we're at it create a separated DTS include file to share code with other BCM4709 devices easier. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
2016-06-01ARM: BCM5301X: Enable SPI-NOR on dual flash devicesRafał Miłecki1-0/+4
Commit 1b47b98acce2 ("ARM: BCM5301X: Add DT entry for SPI controller and NOR flash") enabled SPI-NOR device on routers using serial flash only. However there are also devices with two flash memories: 1) Small SPI attached flash used mostly for booting 2) Bigger NAND used mostly for storing firmware On such devices we still need SPI-NOR e.g. to access NVRAM data.

2016-04-13ARM: BCM5301X: Set vcc-gpio for USB controllers of few devicesRafał Miłecki1-0/+5
There are few devices that have USB power controlled using GPIO. Linux USB host driver (bcma-hcd) already supports this by reading vcc-gpio from DT. Set it properly for all known devices. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
2015-06-06ARM: BCM5301X: add NAND flash chip descriptionHauke Mehrtens1-0/+1
This adds the NAND flash chip description for a standard chip found connected to this SoC. This makes use of generic Broadcom NAND driver with the iProc interface. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
