SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h - Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR - Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack pointer directly, otherwise we use the common calculation. - On some platforms that were using the standard calculation but did not set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them. - On a small number of platforms that were not subtracting GENERATED_GBL_DATA_SIZE do so now via the standard calculation. - CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most board config header files.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mpc83xx: boot time regression, move LCRR setup back to cpu_init_f Commit c7190f02 (retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields) moved the LCRR assignment to after relocation to RAM because of the potential problem with changing the local bus clock while executing from flash. This change unfortunately adversely affects the boot time, as running all code up to cpu_init_r can cause significant slowdown. E.G. on a 8347 board a bootup time increase of ~600ms has been observed: 0.020 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz 0.168 RS: 232 0.172 I2C: ready 0.176 DRAM: 64 MB 1.236 FLASH: 32 MB Versus: 0.016 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz 0.092 RS: 232 0.092 I2C: ready 0.096 DRAM: 64 MB 0.644 FLASH: 32 MB So far no boards have needed the late LCRR setup, so simply revert it for now - If it is needed at a later time, those boards can either do their own final LCRR setup in board code (E.G. in board_early_init_r), or we can introduce a CONFIG_SYS_LCRR_LATE config option to only do the setup in cpu_init_r.

83xx/85xx/86xx: LBC register cleanup Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields some LCRR bits are not documented throughout the 83xx family RMs. New board porters copying similar board configurations might omit setting e.g., DBYP since it was not documented in their SoC's RM. Prevent them bricking their board by retaining power on reset values in bit fields that the board porter doesn't explicitly configure via CONFIG_SYS_<registername>_<bitfield> assignments in the board config file. also move LCRR assignment to cpu_init_r[am] to help ensure no transactions are being executed via the local bus while CLKDIV is being modified. also start to use i/o accessors.

mpc83xx: Store and display Arbiter Event Register values Record the Arbiter Event Register values and optionally display them. The Arbiter Event Register can record the type and effective address of an arbiter error, even through an HRESET. This patch stores the values in the global data structure. Display of the Arbiter Event registers immediately after the RSR value can be enabled with defines. The Arbiter values will only be displayed if an arbiter event has occured since the last Power On Reset, and either of the following defines exist: #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and and type register values #define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter event register values Address Only transactions are one of the trapped events that can register as an arbiter event. They occur with some cache manipulation instructions if the HID0_ABE (Address Broadcast Enable) is set and the memory region has the MEMORY_COHERENCE WIMG bit set. Setting: #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address only events, so that it can still capture other real problems.
