From 0b2fa98aa5e5dbdac4f5e2b2f67a34cc34dcc6b8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 16 Dec 2020 21:20:06 -0700 Subject: linker_lists: Fix alignment issue The linker script uses alphabetic sorting to group the different linker lists together. Each group has its own struct and potentially its own alignment. But when the linker packs the structs together it cannot ensure that a linker list starts on the expected alignment boundary. For example, if the first list has a struct size of 8 and we place 3 of them in the image, that means that the next struct will start at offset 0x18 from the start of the linker_list section. If the next struct has a size of 16 then it will start at an 8-byte aligned offset, but not a 16-byte aligned offset. With sandbox on x86_64, a reference to a linker list item using ll_entry_get() can force alignment of that particular linker_list item, if it is in the same file as the linker_list item is declared. Consider this example, where struct driver is 0x80 bytes: ll_entry_declare(struct driver, fred, driver) ... void *p = ll_entry_get(struct driver, fred, driver) If these two lines of code are in the same file, then the entry is forced to be aligned at the 'struct driver' alignment, which is 16 bytes. If the second line of code is in a different file, then no action is taken, since the compiler cannot update the alignment of the linker_list item. In the first case, an 8-byte 'fill' region is added: .u_boot_list_2_driver_2_testbus_drv 0x0000000000270018 0x80 test/built-in.o 0x0000000000270018 _u_boot_list_2_driver_2_testbus_drv .u_boot_list_2_driver_2_testfdt1_drv 0x0000000000270098 0x80 test/built-in.o 0x0000000000270098 _u_boot_list_2_driver_2_testfdt1_drv *fill* 0x0000000000270118 0x8 .u_boot_list_2_driver_2_testfdt_drv 0x0000000000270120 0x80 test/built-in.o 0x0000000000270120 _u_boot_list_2_driver_2_testfdt_drv .u_boot_list_2_driver_2_testprobe_drv 0x00000000002701a0 0x80 test/built-in.o 0x00000000002701a0 _u_boot_list_2_driver_2_testprobe_drv With this, the linker_list no-longer works since items after testfdt1_drv are not at the expected address. Ideally we would have a way to tell gcc not to align structs in this way. It is not clear how we could do this, and in any case it would require us to adjust every struct used by the linker_list feature. One possible fix is to force each separate linker_list to start on the largest possible boundary that can be required by the compiler. However that does not seem to work on x86_64, which uses 16-byte alignment in this case but needs 32-byte alignment. So add a Kconfig option to handle this. Set the default value to 4 so as to avoid changing platforms that don't need it. Update the ll_entry_start() accordingly.

The idea is that devices can 'request' a sequence number and then the conflicts are resolved when the device is probed. This makes things complicated in a few cases, since we don't really know what the sequence number will end up being. We want to honour the bind-time requests if at all possible, but in fact the only source of these at present is the devicetree aliases. Since we have the devicetree available at bind time, we may as well just use it, in the hope that the required processing will turn out to be useful later (i.e. the device actually gets used). Add a new 'sqq' member, the bind-time sequence number. It operates in parallel to the old values for now. All devices get a valid sqq value, i.e. it is never -1. Drop an #ifdef while we are here.

This patch drops spi_slave->speed member and adds caching of bus speed/mode in dm_spi_bus struct. It also updates spi_claim_bus() to call spi_set_speed_mode() if either speed or mode is different from what the bus is currently configured for. Current behavior is to only take into account the speed, but not the mode, which seems wrong.

For example SPL code size for px30-core-ctouch2-px30 increased by 40 bytes. To address this we can take advantage of the fact that some of the ofnode functions are only called a few times in SPL, so it is worth inlining them. Add new Kconfig options to control this. These functions are not inlined for U-Boot proper, since this increases code size.
