[U-Boot] [RFC PATCH] vexpress: Check TC2 firmware support before defaulting to nonsec booting

The firmware on TC2 needs to be configured appropriately before booting in nonsec mode will work as expected, so test for this and fall back to sec mode if required. Signed-off-by: Jon Medhurst --- This is an implementation of Andre's suggestion in

[U-Boot] [PATCH] ARM: vexpress: Remove virt and nonsec support for TC2

When CPU's come out of reset they are in secure state supervisor mode, so this is the state Linux kernel entry point is called in when it brings up secondary CPU cores or the primary CPU restarts after power management has sent it through an off/on transition. As U-Boot starts the kernel in

[U-Boot] [PATCH v2] MMC: PL180: Fix infinite loop with VExpress extended fifo implementation

The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining
