2020-07-27armv8: layerscape: properly use CPU_RELEASE_ADDRMichael Walle
The generic armv8 code already has support to bring up the secondary cores. Thus, don't hardcode the jump in the layerscape lowlevel_init to the spin table code; instead just return early and let the common armv8 code handle the jump. This way we can actually use the CPU_RELEASE_ADDR feature.

2020-07-27armv8: layerscape: fix spin-table supportMichael Walle
Spin tables are broken with bootefi. This is because - in contrast to the booti call chain - there is no call to smp_kick_all_cpus(). Due to this missing call the secondary CPUs are never released from their "wait for interrupt state", see secondary_boot_func() in lowlevel.S. Originally, this "wait for interrupt" is there to make sure, the spin table is cleared before the secondary cores read it for the first time. But the boot flow for the layerscape architecture is different from that. The CPUs are release from their BootROM _after_ U-Boot's spin-table is cleared, see fsl_layerscape_wake_seconday_cores() in mp.c. Thus, there is no need to wait for this interrupt and no need for kicking all cores on cpu_release. An atomic 64bit write to the spin-table and a "sev" is sufficient.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-07-07arm64: issue ISB after updating system registersVolodymyr Babchuk
ARM Architecture reference manual clearly states that PE pipeline should be flushed after changes to some system registers. Refer to paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI 0487B.a). Failing to issue instruction synchronization barrier can lead to spurious errors, like synchronous exception when accessing FPU registers. This is very prominent on CPUs with long instruction pipeline, like ARM Cortex A72. This change fixes the following U-Boot panic: "Synchronous Abort" handler, esr 0x1fe00000 elr: 00000000800948cc lr : 0000000080091e04 x0 : 00000000801ffdc8 x1 : 00000000000000c8 x2 : 00000000800979d4 x3 : 00000000801ffc60 x4 : 00000000801ffd40 x5 : ffffff80ffffffd8 x6 : 00000000801ffd70 x7 : 00000000801ffd70 x8 : 000000000000000a x9 : 0000000000000000 x10: 0000000000000044 x11: 0000000000000000 x12: 0000000000000000 x13: 0000000000000000 x14: 0000000000000000 x15: 0000000000000000 x16: 000000008008b2e0 x17: 0000000000000000 x18: 00000000801ffec0 x19: 00000000800957b0 x20: 00000000000000c8 x21: 00000000801ffdc8 x22: 000000008009909e x23: 0000000000000000 x24: 0000000000000000 x25: 0000000000000000 x26: 0000000000000000 x27: 0000000000000000 x28: 0000000000000000 x29: 00000000801ffc50 Code: a94417e4 a90217e4 a9051fe6 a90617e4 (3d801fe0) While executing instruction str q0, [sp, #112] in vsnprintf() prologue.

2020-05-17efi_loader: round the memory area in efi_add_memory_map()Michael Walle
Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module. Thus rename it to efi_add_memory_map_pg() and make it static to prevent further misuse outside the module. Signed-off-by: Michael Walle <michael@walle.cc> Add missing comma in sunxi_display.c.

2020-05-10imx: imx8qm/qxp: Recover SPL data section for partition rebootPeng Fan
When doing partition reboot, the boot image won't be reloaded by ROM, it is just CPU reset to boot entry. The SW has to keep the boot image inside the RAM unchanged. It includes both the TEXT section and DATA section. For SPL, the problem is DATA section will be updated at runtime, so in next partition reboot the data is not same as the initial value from cold boot. If any code depends on the initial value, then it will have problem. This patch introduces a mechanism to recover the data section for partition reboot. It adds a new section in image for saving data section. When from cold boot, the data section will be saved to that new section at SPL early phase. When from partition reboot, the data section will be restored from the new section. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
