2017-12-07Revert "sandbox: Drop special case console code for sandbox"Simon Glass
While sandbox works OK without the special-case code, it does result in console output being stored in the pre-console buffer while sandbox starts up. If there is a crash or a problem then there is no indication of what is going on. For ease of debugging it seems better to revert this change also.

2017-11-26usb: hub: identify the hub-device to usb_hub_reset_devicesPhilipp Tomsich
When usb_hub_reset_devices is called, it should be passed both an indicator which hub it should operate on and what port number (local to that hub) should be reset. Previously, the usb_hub.c code did not include such context and always started resets from port number 1, performing multiple reset-requests for the same devices: /* * Reset any devices that may be in a bad state when applying * the power. This is a __weak function. Resetting of the devices * should occur in the board file of the device. */ for (i = 0; i < dev->maxchild; i++) usb_hub_reset_devices(i + 1); This adds an additional 'hub' parameter to usb_hub_reset_devices that provides the context to fully qualify the port-number in. Existing implementations are changed to accept and ignore the new parameter.

2017-11-26spl: fit: add SPL_FIT_IMAGE_TINY config to reduce code-sizePhilipp Tomsich
A minor code-size increase from the changes for tracking the os-type of FIT images and from infrastructure for recording the loadables into the the loaded FDT, broke the builds for sun50i and some OMAP2+ devices. This change adds a new config option (enabled by default for MACH_SUN50I, MACH_SUN50I_H5 and ARCH_OMAP2PLUS) that does skips these processing steps (bringing code size down to below the limit again). The os-type is not evaluated, but assumed to be IH_OS_UBOOT (i.e. taking the code-paths intended for backward-compatibility). Note that enabling this config option precludes any useful downstream processing, such as utilising a special calling convention for ATF or OPTEE, based on the os-type of the loadables.

2017-11-26spl: atf: introduce spl_invoke_atf and make bl31_entry privatePhilipp Tomsich
This adds a new interface spl_invoke_atf() that takes a spl_image_info argument and then derives the necessary parameters for the ATF entry. Based on the additional information recorded (into /fit-images) from the FIT loadables, we can now easily locate the next boot stage. We now pass a pointer to a FDT as the platform-specific parameter pointer to ATF (so we don't run into the future headache of every board/platform defining their own proprietary tag-structure), as FDT access is already available in ATF. With the necessary infrastructure in place, we can now update the support for the ARM Trusted Firmware to dispatch into the spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is loaded.

2017-11-26spl: fit: implement recording of loadables into /fit-imagesPhilipp Tomsich
If a FDT was loaded (e.g. to append it to U-Boot image), we store it's address and record information for all loadables into this FDT. This allows us to easily keep track of images for multiple privilege levels (e.g. with ATF) or of firmware images preloaded into temporary locations (e.g. PMU firmware that may overlap the SPL stage).

2017-11-26spl: fit: implement fdt_record_loadablePhilipp Tomsich
During the loading of more complex FIT images (e.g. when the invoked next stage needs to find additional firmware for a power-management core... or if there are multiple images for different privilege levels started in parallel), it is helpful to create a record of what images are loaded where: if a FDT is loaded for one of the next stages, it can be used to convey the status and location of loadables. This adds a fdt_record_loadable() function that can be invoked to record the status of each loadable below the /fit-images path.

2017-11-26spl: fit: simplify logic for FDT loading for non-OS bootsPhilipp Tomsich
To better support bootin through an ATF or OPTEE, we need to streamline some of the logic for when the FDT is appended to an image: depending on the image type, we'd like to append the FDT not at all (the case for the OS boot), to the 'firmware' image (if it is a U-Boot) or to one of the loadables (if the 'firmware' is an ATF, an OPTEE, or some other image-type and U-Boot is listed in the loadabled). To achieve this goal, we drop the os_boot flag and track the type of image loaded. If it is of type IH_OS_U_BOOT, we append the FDT.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err().

2017-10-04printk: collect printk stuff into <linux/printk.h> with loglevel supportMasahiro Yamada
When we import code from Linux, with regular re-sync planned, we want to use printk() and pr_*(). U-Boot does not support them in a clean way. So, people end up with local macros, or compat headers here and there, then we occasionally see build errors of definition conflicts. We have include/linux/compat.h, but putting all sorts of unrelated things into a single header is just a temporal workaround. Hence this patch, to find the best home for all printk variants. If you want to use printk() and friends, please include <linux/printk.h>. This header is self-contained, and pulls in only a few headers. When I was testing this clean-up, I noticed the image size exceeded its platform limit on some boards. This is because all pr_*() that were previously defined as no-op in include/linux/mtd/mtd.h (unless CONFIG_MTD_DEBUG is set), are now enabled. To make such boards happy, this commit also implements CONFIG_LOGLEVEL. The concept is similar to the kernel parameter "loglevel". (Actually, the Kconfig help message was taken from kernel-paremeter.txt of Linux) Messages with a loglevel smaller than console loglevel will be printed. The difference is the loglevel is build-time determined. To save the image size, lower priority pr_*() are compiled out. I set the default of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages are compiled in. I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.
