2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-04-28spl: Split sprintf, strto* from SPL serial in KconfigAlex Kiernan
When SPL serial is disabled, callers who need sprintf or strtoul fail because their inclusion is guarded by CONFIG_SPL_SERIAL_SUPPORT/ CONFIG_TPL_SERIAL_SUPPORT. Split printf, sprintf and strto into their own entries and then select all of them if SERIAL_SUPPORT is enabled to match the current behaviour. Include panic.o unconditionally as it can be called from anywhere which uses BUG_ON(). Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com>
2018-04-28lib/rsa: Kconfig: Remove superfluous 'depends on RSA'Eugeniu Rosca
RSA_SOFTWARE_EXP and RSA_FREESCALE_EXP are wrapped inside: if RSA ... endif So, remove the redundant "depends on RSA" from their depends expression. In addition, move SPL_RSA into the same "if RSA ... endif" block, since its only direct dependeny is CONFIG_RSA. This tidies up and simplifies reading of lib/rsa/Kconfig. No functional change intended. Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-04-23efi_loader: correcty determine total device path lengthHeinrich Schuchardt
Device paths may consist of multiple instances. Up to now we have only considered the size of the first instance. For the services of the EFI_DEVICE_PATH_UTILITIES_PROTOCOL in most cases the total length of the device path is relevant. So let's rename efi_dp_size() to efi_dp_instance_size() and create a new function efi_dp_size() that calculates the total device path length.

2018-04-05efi_loader: new functions to print loaded image informationHeinrich Schuchardt
Introduce functions to print information about loaded images. If we want to analyze an exception in an EFI image we need the offset between the PC and the start of the loaded image. With efi_print_image_info() we can print the necessary information for a single image, e.g. UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi' efi_print_image_infos() provides output for all loaded images.

2018-04-04efi_loader: initialize device path on allocPatrick Wildt

2018-04-04efi_loader: Fix network DP with DM_ETHAlexander Graf
When CONFIG_DM_ETH is set, we assemble the device path properly with a full device hierarchy. Our helper function dp_fill() even put the MAC node itself in it for us. However, for non-DM compatibility we also have code in that added the MAC node manually. That code now runs on top of the existing MAC node: Handle 0x3db2f6b0 /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ] /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1) /MacAddr(b8:27:eb:e1:81:47,57)/EndEntire We obviously don't need the additional node and in fact, grub chokes on it and fails to match the DP against the ethernet device node. So this patch moves the additional MAC node into the non-DM code path: Handle 0x3db3fde0 /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ] /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1) /EndEntire While at it, we also mark the non-DM MAC node as ethernet.

2018-04-04efi_loader: Optimize GOP moreAlexander Graf
The GOP path was optimized, but still not as fast as it should be. Let's push it even further by trimming the hot path into simple 32bit load/store operations for buf->vid 32bpp operations. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-04-04efi_loader: Optimize GOP switchAlexander Graf
We usually try to compile for size, not for speed. Unfortunately with the more powerful GOP infrastructure to handle all sorts of GOP operations, we end up slowing down our copying hot path quite a lot. So this patch moves the 4 possible GOP operation modes into separate functions which call a common function again. The end result of that is more optimized code that can properly do constant propagation throughout its switch() statements and thus removes compares in the hot path.

2018-04-04efi_loader: use __always_inline for pixel conversionHeinrich Schuchardt

2018-04-04efi_loader: use TPL_NOTIFY for network timer eventHeinrich Schuchardt
We use a timer to poll the network. iPXE is used for booting from iSCSI drives. It has been changed to run at TPL_CALLBACK most of the time (which is not what the UEFI spec recommends).

2018-04-04efi_loader: correctly support parameter delta in BltHeinrich Schuchardt
In the Blt service of the EFI_GRAPHICS_OUTPUT_PROTOCOL the parameter delta is measured in bytes and not in pixels. The coding only supports delta being a multiple of four. The UEFI specification does not explicitly require this but as pixels have a size of four bytes we should be able to assume four byte alignment. The corresponding unit test is corrected, too.
