With DM enabled, this patch enables DM_SERIAL and removes the NS16550 initialization from da850_lowlevel since the driver will take care of that itself. Signed-off-by: Adam Ford <aford173@gmail.com>

AM654 allows for booting from primary or backup boot media. Both media can be chosen individually based on switch settings. ROM looks for a valid image in primary boot media, if not found then looks in backup boot media. In order to pass this boot media information to boot loader, ROM stores a value at a particular address. Add support for reading this information and determining the boot media correctly.

2018-09-11arm: K3: Update _start instructionLokesh Vutla
On K3 family SoCs, once the ROM loads image on R5, M3 resets R5 and expects to start executing from 0x0. In order to handle this ROM updates the boot vector of R5 such that first 64 bytes of image load address are mapped to 0x0. In this case, it is SPL's responsibility to jump to the proper image location. So, update the PC with address of reset vector(like how other exception vectors are handled), instead of branching to reset.

2018-09-10Remove <inttypes.h> includes and PRI* usages in printf() entirelyMasahiro Yamada
In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

2018-09-10arm: armv7-a: Compile and tune for armv7-a instead of armv5Adam Ford
arch/arm/Makefile references armv5 for backwards compatibility with older compilers. This patch removes those references to armv5, since by now newer compilers are required which should have armv7 support enabled. The Makefile also also has a list of options for mtune, but the entry for CONFIG_CPU_V7A is empty, so this patch tunes the CPU_V7A architecture to generic-armv7-a.

2018-09-07ARM: Specify aligned address for secure section instead of using attributesChen-Yu Tsai
In commit a1274cc94a20 ("ARM: Page align secure section only when it is executed in situ"), we used output section attributes (the "ALIGN" keyword after the colon) to specify the alignment requirements. Using the constant "COMMONPAGE" there was recently broken in binutils 2.31 [1]. Binutils maintainer Alan Modra suggested the former method would still work. Since both methods achieve the same result, this patch does just that. This fixes the "reboot after bootm" issue we've been seeing on sunxi when booting non-secure.

2018-09-04watchdog: mx25: use the imx_watchdog driver for mx25Martin Kaiser
The existing imx_watchdog driver is compatible with mx25 chipsets. Add a WDOG1_BASE_ADDR define for the base address and enable the driver in watchdog's Makefile. To use the driver, a board must define CONFIG_IMX_WATCHDOG and CONFIG_HW_WATCHDOG. This fixes an issue when booting an mx25 chip via usb/serial. In this case, the boot rom will always enable the watchdog. If u-boot is running in interactive mode and the watchdog is not serviced, the system is rebooted when the watchdog expires.
