2019-10-08sandbox: pci: Create a new sandbox_pci_read_bar() functionSimon Glass
The code in swapcase can be used by other sandbox drivers. Move it into a common place to allow this.

2019-10-08sandbox: pci: Move pci_offset_to_barnum() to pci.hSimon Glass
This function is useful in PCI emulators. More it into the header file to avoid duplicating it in other drivers. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08sandbox: pci: Drop the get_devfn() methodSimon Glass
This method is not used anymore since the bus/device/function of PCI devices can be obtained from their (parent's per-child) platform data. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08sandbox: swap_case: Use statics where possibleSimon Glass
Some functions and a struct should be marked static since they are not used outside this file. Update them. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08sandbox: Rename PCI ID for swap_case to be more specificSimon Glass
Rename this ID to SANDBOX_PCI_SWAP_CASE_EMUL_ID since it is more descriptive and allows us to add new PCI emulators without any conflict or confusion. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-07-10test: dm: Add a test for PCI Enhanced AllocationAlex Marginean
This test is built on top of the existing swap_case driver. It adds EA capability structure support to swap_case and uses that to map BARs. BAR1 works as it used to, swapping upper/lower case. BARs 2,4 map to a couple of magic values. Signed-off-by: Alex Marginean <alexm.osslist@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
2018-11-14test: dm: pci: Add cases for finding next PCI capability APIsBin Meng
Add test cases to cover the two newly added PCI APIs: dm_pci_find_next_capability() & dm_pci_find_next_ext_capability(). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-08-08test: dm: pci: Add cases for finding PCI capability APIsBin Meng
Add several PCI capability and extended capability ID registers in the swap_case driver, so that we can add test case for dm_pci_find_capability() and dm_pci_find_ext_capability(). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

This adds a U_BOOT_PCI_DEVICE() declaration to the swap_case driver. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-08-08pci: sandbox: swap_case: Preserve space indicator bit in BAR registersBin Meng
With the newly added testing of more than one device, we get: => ut dm pci_swapcase Test: dm_test_pci_swapcase: pci.c test/dm/pci.c:88, dm_test_pci_swapcase(): "tHIS IS A tESt" = ptr: Expected "tHIS IS A tESt", got "this is a test" Test: dm_test_pci_swapcase: pci.c (flat tree) test/dm/pci.c:88, dm_test_pci_swapcase(): "tHIS IS A tESt" = ptr: Expected "tHIS IS A tESt", got "this is a test" Failures: 2 The failure only happens on the 2nd swap_case device on the PCI bus. The case passes on the 1st device. It turns out the swap_case driver does not emulate bit#0 in BAR registers as a read-only bit. This corrects the implementation.

2018-06-19sandbox: swap_case: Increase number of base address regsSimon Glass
At present the code overruns the bar[] array. Fix this. At the same time, drop the leading / from the "/spl" path so that we can run U-Boot SPL with: spl/u-boot-spl rather than requiring: /path/to/spl/u-boot-spl Reported-by: Coverity (CID: 131199) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
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>

2015-04-18dm: sandbox: Add a emulated PCI device as an exampleSimon Glass
This device sits on the sandbox PCI bus and provides a case-swapping service for sandbox. It illustrates the use of both PCI I/O and PCI memory accesses. Signed-off-by: Simon Glass <sjg@chromium.org>
