Add a bootcmd_sunxi_compat value to the default environment when building with CONFIG_OLD_SUNXI_KERNEL_COMPAT, this way people who occasionally want to boot an old kernel can do so by simply typing "run bootcmd_sunxi_compat" rather then needing to have 2 separate setups / sdcards for old and new kernels.

2015-09-29sunxi: add "fel" boot targetBernhard Nortmann
This patch makes use of the previous changes to add a new "fel" boot target for sunxi boards. When booting via FEL, it's often desirable to work around the absence of other (usable) boot devices - or to be able to override them, deviating from the standard boot sequence. To achieve this, the "fel" boot target gets the highest priority, but won't actually do anything unless certain criteria are met. The "bootcmd_fel" implementation proposed here first tests if an actual FEL boot takes place (using the "fel_booted" env var), and secondly checks that "fel_scriptaddr" was set (originating from the 'loader', i.e. the sunxi-tools fel utility). If both checks pass, then it will try to execute the boot script (boot.scr) at the given address. In case of an error (e.g. an invalid image), the source command might return "false", causing "distro_bootcmd" to proceed with the next boot target.

2015-08-13kconfig: add config option for shell promptNikita Kiryanov
Add option to set shell prompt string from menuconfig and migrate boards globally. The migration is done as follows: - Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the entry moved to their defconfig files. - Boards that defined some kind of #ifdef logic which selects the CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT right before the #ifdef logic and were left alone. - This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h files. This results in a streamlined default value across platforms, and includes the following files: spear-common, sunxi-common, mv-common, ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common. - Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were not updated in their respective defconfig files under the assumption that since they did not explicitly define a value, they're fine with whatever the default is. - On the other hand, boards that relied on a value defined in some <boards>_common.h file such as woodburn_common, rpi-common, bur_am335x_common, ls2085a_common, siemens_am33x_common, and omap3_evm_common, had their values moved to the respective defconfig files. - The define V_PROMPT was removed, since it is not used anywhere except for assigning a value for CONFIG_SYS_PROMPT.

2015-08-08sunxi: Do not add a stdout-path alias to dts on boards without a serial portHans de Goede
Do not add a bogus (pointing to a non existing serial port) stdout-path alias to dts on boards without a serial port. Note that we still define CONS_INDEX as this is used by the SPL where we do not use DM_SERIAL and thus CONFIG_REQUIRE_SERIAL_CONSOLE is not honored. We are getting away with this because the sun5i die actually has an uart0, which in the A13 package is not routed to the outside, so we are simply sending SPL bootup messages to the tx pin at the edge of the die, and they go no further from there... And sofar we only have one A13 board which does not have a serial port, all others do have a serial port. This kinda makes sense since the A13 is a much lower pincount package compared to all the other sunxi SoCs.

2015-05-19console: Fix pre-console flushing via cfb_console being very slowHans de Goede
On my A10 OlinuxIno Lime I noticed a huge (5+ seconds) delay coming from console_init_r. This turns out to be caused by the preconsole buffer flushing to the cfb_console. The Lime only has a 16 bit memory bus and that is already heavy used to scan out the 1920x1080 framebuffer. The problem is that print_pre_console_buffer() was printing the buffer once character at a time and the cfb_console code then ends up doing a cache-flush for touched display lines for each character. This commit fixes this by first building a 0 terminated buffer and then printing it in one puts() call, avoiding unnecessary cache flushes. This changes the time for the flush from 5+ seconds to not noticable. The downside of this approach is that the pre-console buffer needs to fit on the stack, this is not that much to ask since we are talking about plain text here. This commit also adjusts the sunxi CONFIG_PRE_CON_BUF_SZ to actually fit on the stack. Sunxi currently is the only user of the pre-console code so no other boards need to be adjusted.

2015-02-21sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernelsSiarhei Siamashka
Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option, which makes it go out of its way in limiting the selection of PLL clock frequencies and PMIC voltages in order not to upset outdated buggy sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set, then booting such old kernels exhibits various failures at runtime. This is very user unfriendly, and there were already several incidents when people wasted their time being hit by these runtime failures and trying to debug them. The right solution is not to add hacks and workarounds to the mainline U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact, the updated sunxi-3.4 kernels already exist. Still we need to follow the 'Principle of Least Surprise' and U-Boot needs to ensure that the old buggy kernels are not getting happily booted when the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch addresses this particular issue. This patch makes U-Boot store the 'compatibility revision' number in the top 4 bits of the machine id and pass it to the kernel. The old buggy kernels will fail to load with a very much googlable error message on the serial console (the "r1 = 0x100010bb" part of it): "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)" This error message can be documented in the linux-sunxi wiki with proper explanations about how to resolve this situation and where to get the necessary bugfixes for the sunxi-3.4 kernel. The fixed sunxi-3.4 kernels implement a revision compatibility check and clear the top 4 bits of the machine id if everything is alright. By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4 kernel effectively certifies that it has the PLL5 clock speed and AXP209 DCDC3 voltage fixes applied. It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option in U-Boot if the user desires to use an outdated unpatched sunxi-3.4 kernel.

While discussing with some people how to get the Linux kernel to do the right thing wrt sending output to both the serial console and the hdmi out / lcd screen when booting on ARM devices, Grant Likely pointed out that there already is a solution for this. All we need to do is set the /chosen/stdout-path fdt property, and if no console= arguments were specified on the kernel commandline the kernel will honor this and add this device as a console (next to the primary video output on hdmi). And u-boot already has support for setting this, all we need to do is define OF_STDOUT_PATH and then everything will just work ootb, without people needing to meddle with adding console= arguments in extlinux.conf .
