Add symlink from gpl-2.0.txt to a COPYING file
While it is good that the "Licenses/" directory contains the text
for all licenses that are applicable to u-boot code, it is harder
to determine at a glance what the default and/or preferred license
is. While humans can look at the Licenses/README file, this is not
machine parseable, making it tricky for license detection tools to
automatically determine/report on the overall / aggregate u-boot
license.
The project previously had a top level COPYING file containing a
short blurb, followed by the GPL license text. This was removed
back in commit
eca3aeb352c964bdb28b8e191d6326370245e03f when
the "Licenses/" directory was introduced. For the benefit of
automated tools, it is helpful to retain a top level COPYING
file in the repository. Rather than duplicate the license text,
however, a symlink from the Licenses/gpl-2.0.txt file should
suffice.

Figure 104.3b Initial Setting of PCIEC(example), third quarter of the figure

Register 0xf8 bit 18 is 0 immediately after write to PCIERSTCTRL1 and is set
to 1 in less than 1 ms afterward. The current readl_poll_timeout() break
condition is inverted and returns when register 0xf8 bit 18 is set to 0,
which in most cases means immediately. In case CONFIG_DEBUG_LOCK_ALLOC=y ,
the timing changes just enough for the first readl_poll_timeout() poll to
already read register 0xf8 bit 18 as 1 and afterward never read register
0xf8 bit 18 as 0, which leads to timeout and failure to start the PCIe
controller.

Secondly, 1400MHz ND mode (Nominal Drive) requiring 0.85V BUCK voltage
was not supported with current power_init_board() PMIC settings. Add
check also for this CPU type and set BUCK voltage accordingly.
Last but not least, add printf() printouts about PMIC voltage mode to

Merge patch series "Fix dma_addr_t for R5 SPL"
Anshul Dalal <anshuld@ti.com> says:
On various TI's K3 platforms boot failure was observed on SPI NOR since the
commit
5609f200d062 ("arm: Kconfig: enable LTO for ARCH_K3"). This issue was
root caused to stack corruption by the 'udma_transfer' function. Where the local
variable 'paddr' of type 'dma_addr_t' was being written to as a 64-bit value
which overwrote the stack frame of the caller (dma_memcpy) as only 32-bits had
been reserved for paddr on the stack, specifically the r4 register in the frame
of dma_memcpy was being overwritten with a 0.
drivers/dma/ti/k3-udma.c:2192:
int udma_transfer(...)
{
...
dma_addr_t paddr = 0;
...
/* paddr was written to as 64-bit value here */
udma_poll_completion(uc, &paddr);
}
drivers/dma/dma-uclass.c:234:
int dma_memcpy(...)
{
dma_addr_t destination;
dma_addr_t source;
int ret;
...
/* This call resolves to udma_transfer */
ret = ops->transfer(...);
...
dma_unmap_single(destination, ...);
dma_unmap_single(...);
return ret;
}
Enabling LTO changed how gcc mapped local variables of dma_memcpy to CPU
registers, where earlier the bug was hidden since the overwritten register
'r4' was allotted to 'ret' but was allotted to 'destination' once LTO was
enabled. And since the overwritten value was 0, the bug remained undetected
as it just meant ret was 0, but having 'destination' set to 0 caused
dma_unmap_single to fail silently leading to boot failures.
The fix entails enabling DMA_ADDR_T_64BIT which changes dma_addr_t from u32 to
u64 for the R5 SPL thus reserving enough space for 'paddr' to prevent the
overflow.

config: arch: k3: enable DMA_ADDR_T_64BIT
ARCH_K3 encompasses both 32 and 64-bit cores on the same SoC, though the
DMA addresses are always 64-bit in size.
With the current implementation, the R5 SPL uses a u32 for dma_addr_t
which leads to data overflow when functions such as k3_nav_*_pop_mem try
to write a 64-bit address to dma_addr_t variable.
In certain cases it leads to stack corruption which manifest as boot
failures on certain compilers, such as SPI boot on GCC 14.2 or 13.3.
Therefore this patch selects CONFIG_DMA_ADDR_T_64BIT for all ARCH_K3.

dma: ti: k3-udma: fix dma_addr_t typecasts
dma_addr_t is used to store any valid DMA address which might not
necessarily be the same size as host architecture's word size. Though
various typecasts in k3's dma and usb driver expect dma_addr_t to be the
same size as the word size.
This leads the compiler to throw a "cast from pointer to integer of
different size" warning when the condition is not met, for example when
enabling CONFIG_DMA_ADDR_T_64BIT for the R5 core.
Therefore this patch fixes the typecasts by using 'uintptr_t' as an
intermediary type which is guaranteed to be the same size as void* on
the host architecture. Thus, eliminating the compiler warning.

Linux kernel should use some separate device tree obtained from another
source anyway. For example the dtb file can be read from /boot directory
in eMMC rootfs partition, either by GRUB or U-Boot. Using U-Boot's
device tree blob to provide it to the kernel (when
CONFIG_DEFAULT_FDT_FILE is set and nobody else overrides this choice)
might lead to undesired effects when booting the OS. For example, if a
user sets "dr_mode" property to "host" value in U-Boot's dts to enable
USB host capabilities in U-Boot, it might confuse usb-conn-gpio driver
in Linux kernel later like this:
platform connector: deferred probe pending: usb-conn-gpio:
failed to get role switch
Disable CONFIG_DEFAULT_FDT_FILE option to avoid any possible confusion.

board: samsung: e850-96: Add bootdev var to choose boot device
Provide a way for the user to select which storage to load the LDFW
firmware from, by setting the corresponding environment variables:
- bootdev: block device interface name
- bootdevnum: block device number
- bootdevpart: partition number
This might be useful when the OS is flashed and booted from a different
storage device than eMMC (e.g. USB flash drive). In this case it should
be sufficient to just set:
=> setenv bootdev usb
=> env save
assuming that the USB drive layout follows the same partitioning scheme
as defined in $partitions.

Make it possible to provide the information about storage device where
LDFW firmware resides to the firmware loading routine. The firmware
loader code shouldn't have that data hard-coded anyway, and it also
allows for implementing more dynamic behavior later, like choosing the
storage device containing LDFW via some environment variables.
No functional change.

board: samsung: e850-96: Add PMIC code
Add functions for configuring voltage regulators on S2MPU12 PMIC chip
for E850-96 board. The chip is accessed by commanding APM core (via
ACPM IPC protocol) to perform corresponding transfers over I3C bus.
The most important regulator being set up is LDO24 used for LAN9514 chip
power. As LAN9514 implements USB hub and Ethernet controller
functionality, it's crucial to enable and configure LDO24 to be able to
use it further. While at it, configure the rest of regulators that might
be needed later, both in the bootloader and in kernel.

Set the environment variable for Ethernet MAC address (ethaddr). Use the

get_chip_id() = 0x236f51c8113
serial# =
00000236f51c8113

mac_addr[2] = 0xf5 // OTP_CHIPID0[31:24]

mac_addr[4] = 0x81 // OTP_CHIPID0[15:8]
mac_addr[5] = 0x13 // OTP_CHIPID0[7:0]
because OTP_CHIPID1 has only 16 significant bits (with actual ID
values), and all 32 bits of OTP_CHIPID0 are significant.

clk: exynos: Fix always true test
In exynos7420_peric1_get_rate the variable ret is declared as an
'unsigned int' but is then used to receive the return value of
clk_get_by_index which returns an int. The value of ret is then tested
for being less than 0 which will always fail for an unsigned variable.
Fix this by declaring ret as an 'int' so that the test for the error
condition is valid.
