powerpc: dts: t104xrdb: fix phy type for FMAN 4/5

2022-04-15T12:18:32+00:00

[ Upstream commit 17846485dff91acce1ad47b508b633dffc32e838 ]

T1040RDB has two RTL8211E-VB phys which requires setting
of internal delays for correct work.

Changing the phy-connection-type property to `rgmii-id`
will fix this issue.

powerpc/fsl/dts: Fix phy-connection-type for fm1mac3

2021-10-13T08:08:19+00:00

[ Upstream commit eed183abc0d3b8adb64fd1363b7cea7986cd58d6 ]

Property phy-connection-type contains invalid value "sgmii-2500" per scheme
defined in file ethernet-controller.yaml.

Correct phy-connection-type value should be "2500base-x".

powerpc/boot: Delete unneeded .globl _zimage_start

2021-09-12T06:56:40+00:00

commit 968339fad422a58312f67718691b717dac45c399 upstream.

.globl sets the symbol binding to STB_GLOBAL while .weak sets the
binding to STB_WEAK. GNU as let .weak override .globl since
binutils-gdb 5ca547dc2399a0a5d9f20626d4bf5547c3ccfddd (1996). Clang
integrated assembler let the last win but it may error in the future.

Since it is a convention that only one binding directive is used, just
delete .globl.

powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c controllers

The i2c controllers on the P1010 have an erratum where the documented
scheme for i2c bus recovery will not work (A-004447). A different
mechanism is needed which is documented in the P1010 Chip Errata Rev L.

powerpc/44x: Adjust indentation in ibm4xx_denali_fixup_memsize

2020-02-11T12:35:45+00:00

commit c3aae14e5d468d18dbb5d7c0c8c7e2968cc14aad upstream.

Clang warns:

../arch/powerpc/boot/4xx.c:231:3: warning: misleading indentation;
statement is not part of the previous 'else' [-Wmisleading-indentation]
        val = SDRAM0_READ(DDR0_42);
        ^
../arch/powerpc/boot/4xx.c:227:2: note: previous statement is here
        else
        ^

This is because there is a space at the beginning of this line; remove
it so that the indentation is consistent according to the Linux kernel
coding style and clang no longer warns.
