* armv8/fsl-lsch3: Fix platform clock calculationYork Sun2015-04-23-4/+3

* armv8/ls2085a: Update common header filePrabhakar Kushwaha2015-04-23-109/+222
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ls2085a_common.h contains hard-coded information for NOR/NAND flash, I2C, DDR, etc. These are platform specific. Move them out of common header file and placed into respective board header files. Move TEXTBASE to 1MB offset to fit NOR flash with up to 1MB sector size. Enable command auto complete. Update prompt symbol. Set fdt_high to 0xa0000000 because Linux requires that the fdt be 8-byte aligned and below 512 MiB. Besides ensuring compliance with the 512 MiB limit, this avoids problems with the dtb being misaligned within the FIT image. Change the MC FW, MC DPL and Debug server NOR addresses in compliance with the NOR flash layouts for 128MB flash. Add PCIe macros. Enable "loadb" command. Disable debug server. Enable workaround for erratum A008511. Stop reset on panic for postmortem debugging.

* serial: pl01x: fix PL010 regressionLinus Walleij2015-04-21-2/+11
| | | | | | | | | | | | | | | | | | | | commit aed2fbef5e9a0ab5a7cd01e742039a962f0b24ef "dm: serial: Tidy up the pl01x driver" caused a regression on (real hardware) PL010 by omitting to update the line control register when switching baudrate. Fix this by inlining the missing write to the baud control register. Also renaming the set_line_control() function to pl011_set_line_control() since this function is clearly PL011-specific, and it won't suffice to call that to set up line control.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When accessing PHY registers it is often desirable to only update selected bits, so it is necessary to first read the current value before writing back an modified value with the relevant bits updated. To simplify this and to allow such operations to be incorporated into simple shell scripts propose adding a 'modify' option to the existing mii command, which takes a mask indicating the bits to be updated in addition to a data value containing the new bits, ie, <updated> = (<data> & <mask>) | (<current> & ~<mask>).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have interrupts enabled by default. If the interrupt is not treated later by the OS and the PHY's interrupt line is enabled and shared with other interrupts, the system will get an interrupt storm. This patch disables the interrupt for PHY devices that use one of the current Realtek Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L) have the interrupt masked. In this case, the functionality of the PHY should not be afected since this patch brings INER and INSR registers to their default values.

Thus, saveenv overwrites the U-Boot image and bricks the board. I tried to find out when U-Boot grew beyond this point, but there is a long stretch in the history where this board did not build -- and AFAICT when it did fit in 384 KiB, it was missing vital features such as fdt support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot does not have system calls (the services it exposes to standalone commands use a different mechanism), so the syscall handler is dead code. It's also broken code, as it assumes it is located at 0xc00 -- while even before the patch to stop relocating exception vectors to 0, U-Boot had the syscall at 0x900. The critical and machine check return paths are never called -- the regular exception return path is used instead, which works because xSRR0/1 have already been saved and can be restored via the regular SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck inside another exception prolog/epilog).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Booke does not require exception vectors to be located at address zero. U-Boot was doing so anyway, simply because that's how it had been done on other PPC. The downside of this is that once the OS is loaded to address zero, the exception vectors have been overwritten -- which makes it difficult to diagnose a crash that happens after that point. The IVOR setup and trap entry code is simplified somewhat as a result. Also, there is no longer a need to align individual exceptions on 0x100 byte boundaries.
