ARC: [plat-hsdk]: Add missing FIFO size entry in GMAC node

2019-06-25T03:34:48Z

[ Upstream commit 4c70850aeb2e40016722cd1abd43c679666d3ca0 ] Add the binding for RX/TX fifo size of GMAC node.

ARC: [plat-hsdk]: Add missing multicast filter bins number to GMAC node

2019-06-25T03:34:48Z

[ Upstream commit ecc906a11c2a0940e1a380debd8bd5bc09faf454 ] GMAC controller on HSDK boards supports 256 Hash Table size so we need to add the multicast filter bins property. This allows for the Hash filter to work properly using stmmac driver.

ARC: [hsdk] Make it easier to add PAE40 region to DTB

2019-04-02T19:11:01Z

1. Bump top level address-cells/size-cells nodes to 2 (to ensure all down stream addresses are 64-bits, unless explicitly specified otherwise (in "soc" bus with all peripherals) 2. "memory" also specified with address/size 2 3. Add a commented reference for PAE40 region beyond 4GB physical address space Signed-off-by: Vineet Gupta

ARC: DTB: [scripted] fix node name and address spelling

2019-02-25T16:52:16Z

1. Remove "0x" prefix from unit-address of node names ----------------------->8------------------------ sed -i 's/@0x/@/g' arch/arc/boot/dts/*.dts* ----------------------->8------------------------ 2. Make all hex addresses lowercase: ----------------------->8------------------------ sed -i 's/@$[0-9A-Za-z]*$/@\L\1/g' arch/arc/boot/dts/*.dts* sed -i 's/0x$[0-9A-Za-z]*$/0x\L\1/g' arch/arc/boot/dts/*.dts* ----------------------->8------------------------ Inspired by [1] and the like.

ARC: [plat-hsdk] Enable DW APB GPIO support

ARC: [plat-axs*/plat-hsdk]: Allow U-Boot to pass MAC-address to the kernel

2018-08-27T16:00:36Z

Otherwise kernel uses random MAC which is not very conveniet. With that change in place use might set desired MAC in U-Boot with "setenv ethaddr 11:22:33:44:55:66", save environment and then from boot to boot the same MAC will be used by the kernel. One other note for this to happen it's required to pass board's .dtb in U-Boot's "bootm" command like that: ------------------->8----------------- bootm 0x82000000 - 0x84000000 ------------------->8----------------- Here 0x82000000 is location of uImage while 0x80000000 is location of either axs10x.dtb or hsdk.dtb previously loaded from SD-card, USB storage or TFTP server.

kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers

2018-04-07T10:04:02Z

GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped A couple of makefiles mark such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. Another difference is that .PRECIOUS works with pattern rules whereas .SECONDARY does not. .PRECIOUS: $(obj)/%.lex.c works, but .SECONDARY: $(obj)/%.lex.c has no effect. However, for the reason above, I do not want to use .PRECIOUS which could cause obscure build breakage. The targets specified as .SECONDARY must be explicit. $(targets) contains all targets that need to include .*.cmd files. So, the intermediates you want to keep are mostly in there. Therefore, mark $(targets) as .SECONDARY. It means primary targets are also marked as .SECONDARY, but I do not see any drawback for this. I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This will make Kbuild search for non-existing .*.cmd files, but this is not a noticeable performance issue.
