2012-07-24net: sh_eth: add support for SH7757's GETHERYoshihiro Shimoda
SH7757 has 2 ETHERs and 2 GETHERs. This patch supports the SH7757's GETHER. If CONFIG_SH_ETHER_USE_GETHER is defined using SH7757, the driver handles the GETHER. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
2012-07-24net: sh_eth: modify the definitions of regsiterYoshihiro Shimoda
The previous code had many similar definitions in each CPU. This patch borrows from the sh_eth driver of Linux kernel. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
2012-07-24net: sh_eth: add SH_ETH_TYPE_ conditionYoshihiro Shimoda
At the moment, the driver supports the following CPUs: - GETHER (Gigabit Ethernet) : SH7763, SH7734 - ETHER (Fast Ethernet) : SH7724, SH7757 And the driver had the following "#if": #if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734) #if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724) - Those are for GETHER #if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757) - This is for ETHER So, for clean up the code, this patch adds SH_ETH_TYPE_GETHER and SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if". Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
2012-07-24net: sh_eth: clean up for the SH7757's codeYoshihiro Shimoda

2012-07-19net: fec_mxc: Fix MDC for xMIIbenoit.thebaudeau@advans
The MDC signal is available on all xMII (i.e. 'not 7-wire') interfaces, so mii_speed has to be set for all these interfaces, and not only for MII. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> Cc: Stefano Babic <sbabic@denx.de>
2012-07-19net: fec_mxc: Fix setting of RCR for xMIIbenoit.thebaudeau@advans
At least on i.MX25, the RMII mode did not work, which is fixed by this patch. The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set it accordingly. According to the xMII and 7-wire (aka GPSI) standards, full duplex should be available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may support full duplex for 7-wire too, but the reference manual does not say that, so avoid an invalid assumption. Actually, the choice between half and full duplex also depends on the endpoint/switch/repeater configuration, so a config option could be added for that, but there has been no need for it so far.

2012-07-11net/designware: Consecutive writes to the same register to be avoidedDinh Nguyen
This commit is an add-on to f6c4191f. There are a few registers where consecutive writes to the same location should be avoided or have a delay. According to Synopsys, here is a list of the registers and bit(s) where consecutive writes should be avoided or a delay is required: DMA Registers: Register 0 Bit 7 Register 6 All bits except for 24, 16-13, 2-1. GMAC Registers: Registers 0-3 All bits Registers 6-7 All bits Register 10 All bits Register 11 All bits except for 5-6. Registers 16-47 All bits Register 48 All bits except for 18-16, 14.

2012-07-11net: tftp: fix type of block arg to store_blockJayachandran Chandrasekharan Nair
The block argument for store_block can be -1 when the tftp sequence number rolls over (i.e TftpBlock == 0), so the first argument to store_block has to be of type 'int' instead of 'unsigned'. In our environment (gcc 4.4.5 mips toolchain), this causes incorrect 'offset' to be generated for storing the block, and the tftp block with number 0 will be written elsewhere, resulting in a bad block in the downloaded file and a memory corruption.

2012-07-11mxs-i2c: Fix internal address byte orderTorsten Fleischer
Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory. These devices require that the high byte of the internal address has to be written first. The mxs_i2c driver currently writes the address' low byte first. The following patch fixes the byte order of the internal address that should be written to the I2C device.

2012-07-11mxc_i2c: remove setting speed at each startTroy Kisky
Other then being very weird, this code was also wrong. For example, say I set speed to 100K. I'll read back the speed as 85937. But the speed is really 85937.5, so we I reset the speed to 85937, I'll get 73660.7. After a couple of transactions my speed is now exactly 68750 so it will remain there.

2012-07-09tegra: define fdt_load/fdt_high variablesStephen Warren

2012-07-09tegra: trimslice: set up serial flash pinmuxStephen Warren
When Trimslice is booted from serial flash, the boot ROM does this, so U-Boot doesn't need to. However, booting from the SD slot for recovery purposes, the boot ROM does not set up the pinmux for serial flash. Add code to U-Boot to set this up, so that an SD-based recovery U-Boot image can upgrade the U-Boot in serial flash.

2012-07-09tegra: bootcmd: start USB only when neededStephen Warren
Instead of initializing USB as soon as bootcmd is executed, defer it until the first boot device that (potentially in the case of network) uses USB is scanned. This avoids initializing USB when booting from MMC, so speeds that up. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-07-09tegra: bootcmd enhancementsStephen Warren
Place the list of searched boot devices, file-system types, boot file locations/prefixes, and boot script names into variables. This allows the user to override them directly (e.g. to change boot order, or select the specific values they use) without having to edit the main bootcmd and script_boot variables. The default boot order is changed from USB, MMC, DHCP to MMC, USB, DHCP. This speeds up the typical MMC boot case. People who want USB boot can now edit variable boot_targets appropriately. Also, reformat BOOTCMDS_COMMON to fit within 80 columns. Potential future enhancements might be: * Allow boards to specify which of bootcmd_mmc0/... should be defined, based on the HW they contain. * Allow boards to influence the order that the boot targets are added into the boot_targets variable.

2012-07-09tegra: add enterrcm commandStephen Warren
Tegra's boot ROM supports a mode whereby code may be downloaded and flash programmed over a USB connection. On dev boards, this is typically entered by holding down a "force recovery" button and resetting the CPU. However, not all boards have such a button (one example is the Compulab Trimslice), so a method to enter RCM from software is useful. This change implements the command "enterrcm" to do this, and enables it for all Tegra boards by default. Even on boards other than Trimslice, controlling this over a UART may be useful, e.g. to allow simple remote control without the need for mechanical button actuators, or hooking up relays/... to the button.

2012-07-09Add env vars describing U-Boot target boardStephen Warren
