ARM: lpc3250: config: add generic board support

2015-02-16T20:48:36Z

The only LPC3250 board works fine with enabled generic board support, add CONFIG_SYS_GENERIC_BOARD right into the arch config header. Signed-off-by: Vladimir Zapolskiy

sunxi: Support the FEL boot mode in the regular u-boot build

2015-02-16T19:23:52Z

So that the CONFIG_SPL_FEL option is not needed anymore. And the regular SPL binary, generated by the default u-boot build, is now also bootable over USB in the FEL mode. The SPL still can boot from the SD card too. A bunch of system registers need to be saved/restored in order to ensure that the IRQ handler still works in the BROM FEL code after getting control back from the SPL. This is done in the sunxi code instead of abusing ifdefs in 'start.S'. The decision whether to load the main u-boot binary from the SD card or return to the FEL code in the BROM is done at runtime. Signed-off-by: Siarhei Siamashka [hdegoede@redhat.com: Since we now restore various regs before returning to the FEL BROM code we can drop the sunxi specific #ifdefs in start.S] Acked-by: Hans de Goede Signed-off-by: Hans de Goede

sunxi: Normalise FEL support

2015-02-16T19:15:09Z

Make sunxi's FEL code fit with the normal U-Boot boot sequence instead of creating its own. There are some #ifdefs required in start.S. Future work will hopefully remove these. This series is available at u-boot-dm, branch sunxi-working. Signed-off-by: Simon Glass Acked-by: Hans de Goede Signed-off-by: Hans de Goede

arm: spl: Provide for a board-specific loader

2015-02-16T19:15:06Z

Some boards have a special way of loading U-Boot that does not fit with the existing SPL code. For example sunxi uses an 'FEL' mode where U-Boot is loaded over USB. Add a CONFIG option and boot mode for this. Signed-off-by: Simon Glass Acked-by: Siarhei Siamashka Acked-by: Hans de Goede Signed-off-by: Hans de Goede

arm: Allow lr to be saved by board code

2015-02-16T19:14:54Z

The link register value can be required on some boards (e.g. FEL mode on sunxi) so use a branch instruction to jump to save_boot_params() instead of a branch link. This requires a branch back to save_boot_params_ret so adjust the users to deal with this. For exynos just drop the function since it doesn't do anything.

sunxi: dram: Un-inline dram helper functions

2015-02-16T19:05:52Z

Move the dram helper functions to a separate C file, rather then having them as inline helpers in dram.h. This saves 144 bytes in the .text segment for sun6i builds. Signed-off-by: Hans de Goede Reviewed-by: Simon Glass

keystone2: ddr3: eliminate using global ddr3_size variable

2015-02-16T17:41:41Z

KS2 ddr3 initialization uses ddr3_size global variable before u-boot relocation. Even if the variable is not being used after relocation, writing to it corrupts relocation table. This patch removes the global ddr3_size variable and uses local one instead. Signed-off-by: Vitaly Andrianov Tested-by: Nishanth Menon

clock_am43xx:Set the MAC clock to /5 for OPP100

2015-02-16T17:41:40Z

When EMAC is in the boot order, the boot ROM sets OPP50 and the MAC clock is set to /2. SPL needs to change it to /5 for Ethernet to generate the correct txclk. This patch sets it correctly. Signed-off-by: Steve Kipisz

ARM: DRA7-evm: DDR3: Update leveling values

Update the software leveling parameters. This fixes the random crash seen on DRA7-evm. Signed-off-by: Lokesh Vutla
