[U-Boot] [PATCH] buildman: Add GCC 8.1.0 version to tools from kernel.org

[Alexey Brodkin]

Since May 22th toolchains built from GCC 8.1.0 are available at
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/

Unfortunately that pretty trivial bump disclosed a few build
issues, see CI job [1] for all the details.

That's a brief analysis if of any interest:
 1) Wrong use of ARRAY_SIZE in drivers/mtd/nand/atmel_nand.c,
    see [2].

    |       arm:  +   wb45n
    |+In file included from include/linux/delay.h:6,
    |+                 from include/common.h:26,
    |+                 from drivers/mtd/nand/atmel_nand.c:13:
    |+drivers/mtd/nand/atmel_nand.c: In function 'pmecc_get_sigma':
    |+include/linux/kernel.h:46:34: error: division 'sizeof (int16_t * {aka short int *}) / sizeof (int16_t {aka short int})' does not compute the number of array elements [-Werror=sizeof-pointer-div]
    |+ #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
    |+                                  ^
    |+drivers/mtd/nand/atmel_nand.c:252:35: note: in expansion of macro 'ARRAY_SIZE'
    |+  memset(smu, 0, sizeof(int16_t) * ARRAY_SIZE(smu));
    |+                                   ^~~~~~~~~~
    |+drivers/mtd/nand/atmel_nand.c:244:11: note: first 'sizeof' operand was declared here
    |+  int16_t *smu = host->pmecc_smu;
    |+           ^~~

    I guess that's because of 'smu' variable not being an array or a
    pointer to array. Should be trivial to fix.

 2) Issues with .dts on some ARM boards, see [3]:
    |       arm:  +   vinco
    |+arch/arm/dts/at91-vinco.dtb: Warning (reg_format): "reg" property in /ahb/apb/timer at fc024000/timer at 0 has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
    ...and a couple of more of the similar type.

 3) Assembler issues on efi-x86, see [4]:
    |       x86:  +   efi-x86
    |+{standard input}: Assembler messages:
    |+{standard input}:21624: Error: junk at end of line, first unrecognized character is `@'
    |+{standard input}:21669: Error: junk at end of line, first unrecognized character is `@'
    |+{standard input}:21624: Error: can't resolve `end.6766' {.u_boot_list_2_fit_loadable_3 section} - `start.6763' {.u_boot_list_2_fit_loadable_1 section}
    |+{standard input}:21669: Error: can't resolve `end.6766' {.u_boot_list_2_fit_loadable_3 section} - `start.6763' {.u_boot_list_2_fit_loadable_1 section}

 4) -Werror=tautological-compare on some PowerPC boards, see [5]:
    |   powerpc:  +   T1040D4RDB_SPIFLASH
    |+drivers/net/fm/t1040.c: In function 'fman_port_enet_if':
    |+drivers/net/fm/t1040.c:19:53: error: bitwise comparison always evaluates to false [-Werror=tautological-compare]
    |+      ((rcwsr13 & FSL_CORENET_RCWSR13_MAC2_GMII_SEL) ==
    |+                                                     ^~
    |+drivers/net/fm/t1040.c:44:48: error: bitwise comparison always evaluates to false [-Werror=tautological-compare]
    |+   else if ((rcwsr13 & FSL_CORENET_RCWSR13_EC2) ==
    |+

 5) Missing property '#phy-cells' in node in
arch/arm/dts/am335x-boneblack.dts, see [6]:
    |       arm:  +   rastaban pxm2 smartweb etamin thuban draco rut
    |+arch/arm/dts/am335x-boneblack.dtb: Warning (phys_property): Missing property '#phy-cells' in node /ocp/usb at 47400000/usb-phy at 47401300 or bad phandle (referred from /ocp/usb at 47400000/usb at 47401000:phys[0])
